FIVE-CHANNEL DOWNCONVERTER MODULE WITH INPUT RF SWITCH/LIMITER AND LO AMPLIFIER/DIVIDER MODEL SERIES: DSS0818 FEATURES • RF/LO coverage ...... 8 to 18 GHz • Ideal for broadband DF receivers • External IF phase/amplitude adjustments • Channel-to-channel RF tracking Phase ...... ±5° typical Amplitude ...... ±0.5 dB typical • Remote band/blanking/BIT selection

MITEQ’s Model DSS Series integrates our standard broadband double-balanced mixer designs with input limiter protection diodes and IF amplifiers to provide a phase- and amplitude-tracked five-channel downconverter with an integrated LO amplifier/splitter. A three-way input switch/limiter provides remote band/blanking/BIT select and protection from undesired high signal levels. This module is most often used as the “front-end” of a direction-finding system using four antennas in the azimuth, elevation or combined directions and a fifth antenna channel to resolve additional received strong “back or side lobe” signals and to identify the receiver image response. The DSS0818 is also useful as an instantaneous frequency monitor with suitable input frequency to phase encoders (application notes available).

ANGLE INDICATORS ALTERNATIVE APPLICATIONS Can the basic direction-finding receiver also be used to measure incoming frequency?

Yes, by first encoding the received signal into two separate outputs that have a phase difference in direct proportion to their frequency:

MITEQ IQM SERIES

R 0° K SIN Ø 3 dB L RF LIMITER 0° IN 3 dB R 90° VERT. 3 dB HORIZ. L K COS Ø FREQ.TO PHASE ENCODING, CABLE LENGTH

A large cable length difference in the two splitter outputs will yield rapidly varying phase with frequency. If these outputs are applied to a two-channel DF system, the output phase difference, together with knowledge of the encoder cable lengths, can be used to determine input frequency. This is the basic principle of an instantaneous frequency monitor (IFM). In actual practice, several frequency encoders are used with progressively greater frequency resolution, similar to how one reads the dials of a gas or an electric meter.

Questions and Answers about...

MIXER SUBSYSTEMS

Q1: How does the Mixer Product Department define a mixer subsystem?

A1: Generally, the subsystem consists of one or more unique core mixer products from catalog sections 1 through 4, with added input or output components (such as amplifiers, filters, etc.) or simply phase and amplitude matched groups of the core mixer product with associated power dividers for LO, RF or IF.

Q2: What advantages do the subsystems offer the customer?

A2: Subsystems or multifunction components in general are designed to customer specifications. They offer the customer guaranteed input/output performance without worry about the ever-present interface problems between the individual system building blocks. By eliminating intermodule connections, the units offer smaller size and light weight alternatives to assembled connectorized or drop-in components. These multifunction modules utilize, in addition to the mixer capability, our low-noise amplifier technology and our high performance, small size frequency sources. In addition, limiters, switches, filters, couplers, etc., can be incorporated to satisfy the customer’s requirements. Special mul- tichannel assemblies can also be produced in gain and phase matched modules.

Q3: How are the mixer subsystems grouped in this portion of the catalog?

A3: Generally, by market and complexity, because the final cost factor influences how the integration of the subsystem is accomplished. For example, all communication subsystems are intended to lower the overall cost consis- tent with meeting minimum standards of performance, whereas the radar and military subsystems tend to emphasize small size with screened components and state-of-the-art performance at fair prices.

Q3.1: How does MITEQ define millimeter-wave products?

A3.1: The millimeter-wave frequency band is generally accepted to mean from 30 to 300 GHz (1 mm to 0.1 mm wavelengths). For our purpose, however, in this section of the catalog, most products cover up to 50 GHz range. Furthermore, these products tend to utilize the MITEQ core technical advantages of: low-noise RF amplifiers, widest input and output bandwidth mixers, phase-stable oscillators and multipliers.

Q3.2: What are the core advantages of Special Mixer Department’s millimeter-wave products?

A3.2: MITEQ offers the widest input/output bandwidth millimeter-wave up- and downconverters. The most popular triple-balanced unit is TB0440LW1 with an RF and LO bandwidth of 4 to 40 GHz and an IF bandwidth of 0.5 to 20 GHz. Even-harmonic units are also available with less IF bandwidth, but require an LO of only 2 to 20 GHz to downconvert the 4 to 40 GHz, with only 1 to 2 dB higher loss than fundamental mixing. Another key advantage of our department’s mixer products is the capacity to integrate the low-noise amplifiers of other MITEQ departments into a single-interface compensated unit.

Q3.3: What factors influence the choice of high or low side LO placement in wideband millimeter- wave block converters?

A3.3: Generally, one tries to eliminate extra LO x RF mixing products that combine the fundamental RF with harmonics of the LO. These products are highest in level and are also independent of the RF power. For example, the 3LO-RF and 2LO-RF are typically -10 and -25 dBc, respectively, below the desired LO-RF output. In general, for wide bandwidth applications, the LO harmonic mixing products are much more likely to occur with low side mixing. For other applications, where LO x RF spurious products are not an issue, one may want to avoid the spectral inversion of low side mixing by placing the LO above the RF. High side mixing is also frequently employed to eliminate the image response of a wideband receiver without tracking filters. However, another fixed frequency mixer and LO is necessary to make this “dual conversion” technique function. The first double-sideband mixer, IF output is chosen high enough in frequency to produce an image band that falls outside the input RF range. For example, with a 2 to 18 GHz RF input and tracking 24 to 40 GHz LO, the IF is fixed at 22 GHz and the image (2LO - RF) is 46 to 62 GHz. A second mixer and LO would be required to downconvert the 22 GHz first IF to perhaps 1 GHz. Caution is necessary, of course, to reject the image response of the second mixer at 20 or 24 GHz, but this is easier with a fixed frequency relative to the problem of a multioctave input. The first DSB mixer for this application can be a MITEQ TB0440LW1.

Q3.4: How can undesired M x N (LO x RF) spurious products be minimized for a given application, assuming that “high side mixing” and LO power are not options?

A3.4: Triple-balanced mixers traditionally yield the lowest level spur products provided that the diode quads and circuit baluns are constructed to yield high interport isolation. Restricting the RF and IF operating bandwidths will also eliminate many spur products, provided that out-of-band signals are also filtered. The table below shows the maximum possible input RF, percentage bandwidth possible before certain low order products occur. Both fixed LO operations above or below the RF band are shown, each with an octave IF output bandwidth for comparison (reference = Microwave Journal - 1990)

CONDITIONS LO X 2RF 2LO X RF 2LO X 2RF 2LO X 3RF 3LO X 2RF 3LO X 3RF LO > RF IF BW = 0.20 0.40 0.40 0.15 0.40 0.43 0.66 (octave)

LO < RF IF BW = 0.40 0.20 0.40 0.40 0.15 0.43 0.66 (octave) CUSTOM

One can see from the above table that progressively smaller RF bandwidths are required to completely avoid certain PRODUCTS products. The maximum RF bandwidth is also restricted to no more than 40% for the specific case of octave IF bandwidth. This also avoids any overlapping of the input and output bandwidth.

Q3.5: How are the general principles of the previous questions and answers applied to a specific millimeter-wave example?

A3.5: Figure 1 illustrates several 26 to 40 GHz block downconverters, each for the 4 to 18 GHz output band. The spur tables associated with each LO configuration illustrate the advantages of “high side” LO mixing to avoid LO harmonic products. In addition, an octave output bandwidth mixing configuration is shown that utilizes the previous principles of reduced bandwidths to eliminate spurs. However, three separate LOs and preselectors are required. See the following page for Figure 1.

Q4: What are some examples of new mixer subsystems useful to the communication engineer?

A4: Sampling mixers (Model SRD0218LW4) are becoming more prevalent in compact receivers and phase- locked frequency sources because they do not require a high power microwave LO to downconvert the desired signal to a low IF frequency. I/Q sampling mixers can also be used for direct demodulation of biphase signals.

In addition, a new triple-balanced Schottky mixer allows direct multioctave block downconversion of the millimeter- wave 20 to 40 GHz band into an existing 0.5 to 20 GHz receiver. This is possible by using the TB0440LW1 mixer and a MITEQ-fixed frequency (+10 dBm) LO above or below the band of interest. This mixer is also useful for upconverting the 0.5 to 18 GHz band into a fixed Ku-band second converter, thus eliminating the image response without tunable filters.

Q5: What are the basic principles of passive direction finding?

A5: The block diagram below shows a method of measuring the phase angle difference between signals reach- ing amplifiers A and B. All amplitude variations are removed by the IF limiters so the system is relatively insensitive to channel gain differences. A low DC offset double-balanced mixer is used to measure the phase difference, but since the mixer provides the same output voltage for two different phase angles, there is a 180 degree ambiguity in the measurement.

Alternately, one can use an I/Q phase correlator or demodulator to resolve the ambiguity. The I/Q outputs can be used to form a convenient polar display of a received angle. I/Q phase correlators are available at microwave and lower frequencies, although the accuracies are usually higher over narrow bandwidths below 1 GHz.

Actual DF systems use pairs of antennas in the horizontal plane (azimuth) and vertical (elevation) plane. In addition, a fifth channel is sometimes used to resolve angular ambiguities. Frequently the antenna bandwidths are less than the receivers, so that input switching is required. The receiving must also be protected from high input power. The block diagram below illustrates a MITEQ five-channel catalog direction finding subsystem less the I/Q phase detec- tors (see MITEQ Model DSS Series).

Q6: Can the basic direction finding receiver be used to also measure incoming frequency?

A6: Yes, by first encoding the received signal into two separate outputs that have a phase difference in direct proportion to their frequency:

MITEQ IQM SERIES

R 0° K SIN Ø 3 dB L RF LIM 0° INPUT 3 dB R 90° VERT. 3 dB HORIZ. L K COS Ø FREQ.TO PHASE ENCODING, CABLE LENGTH

A large cable length difference in the two splitter outputs will yield rapidly varying phase with frequency. If these outputs are applied to a two-channel DF system, the output phase difference, together with knowledge of the encoder cable lengths, can be used to determine input frequency. This is the basic principle of an instantaneous frequency discriminator (IFM). In actual practice, several frequency encoders are used with progressively greater frequency resolution, much in the same manner that one reads the dials of a gas or electric meter.

Q7: What advantages do sampling mixers offer relative to conventional mixers/LOs for ELINT (Electronic Intelligence Gathering) receiver designs?

A7: Basically, lower cost and power consumption, because the sampling mixer utilizes a UHF LO with internal pulse shaping from a step recovery diode to downconvert an RF at 1 to 20 times higher in frequency. The sampling mixer diodes only charge for a short instant, thus requiring low LO energy relative to the amplifier multiplier chain used to generate the LO power required for a conventional fundamental mixer. The sampling mixer, however, has a limit on the maximum IF bandwidth equal to one half the applied LO frequency (owing to the repetitive frequency response of this mixer). Sampling mixers can also be made in I/Q and image rejection configurations (see Q & A in phase detector section).

Q8: What is meant by electronic warfare (EW) components?

A8: These are component groups that are used in systems that identify and defeat the goals of ground and mis- sile radar systems. A typical component pair might be an I/Q downconverting mixer and upconverting modulator that alters some amplitude or frequency property of a received radar pulse and then retransmits it to act as a decoy reflec- CUSTOM tion. In addition, since EW systems must protect the host vehicle from many different frequency signals with quick reaction times, the operating subsystem bandwidths are wide (often 0.5 to 18 GHz). Airborne EW systems frequently employ small size multiple mixers with a common output or second-stage processing receiver. PRODUCTS

508 MIXER SUBSYSTEMS (CONT.)

Q9: What precautions are necessary when purchasing front-end mixer components for radar receivers?

A9: If the mixer could be subjected to high peak power from transmitter leakage, one must use an input pin diode limiter to ensure that no more than approximately 50 mW/diode or +23 dBm per quad average power. This limit is based upon an average thermal resistance of 160°C/watt for a diode quad mounted on a soft suspended circuit board and maximum diode junction temperature of 125°C with an ambient temperature of 85°C. A single diode limiter available on most MITEQ mixer/preamplifiers will provide protection against a 100 peak power 1 µs pulse and 1 watt average power.

Q10: What choice of front-end components will maximize the dynamic range of radar receivers?

A10: The benefits of low-noise MITEQ AFS or AMF RF preamplifiers are well known and obvious in detecting minimum signal levels. However, the maximum input signal level is often limited by the second-stage image rejection mixer’s 1 dB compression level. A general rule of thumb for the 1 dB compression level of any Schottky barrier mixer is 5 dB less than the LO power. Therefore, if the maximum output power level of the RF preamplifier is +10 dBm, one would need at least a +15 dBm LO power mixer to avoid restricting the dynamic range. A four-channel radar receiver would then require a total of +21 dBm or more LO power. The additional cost and excess noise of the required LO amplifier will impose more design restrictions. As an alternative, a MESFET image rejection mixer generally has an RF 1 dB compression point equal to the LO power, therefore, in this case, the total LO power required is +16 dBm.

The MITEQ Model ARS0506L is an example of a high dynamic range four-channel front end including the LNAs MES- FET IR mixers, IF amplifiers and matched filters. The noise figure is typically 4 dB, but, could also handle up to +5 dBm of input broadband RF noise jamming before overloading. The IF filters used in this phase and amplitude tracked front end have uniform group delay, thus ensuring that paired echoes are at least 40 dB below the main response. PRODUCTS CUSTOM

The problem with this balun had been that the center tap did not exist to separate the IF from the RF or LO.
