  • Common Coaxial Connectors
    Common Coaxial Connectors Below, I present a digest of important information about coaxial connectors. Most of these are for RF and microwave frequencies, but a few of the more common ones used for lower frequencies are included for completeness. Why different connectors? Many coaxial connector types are available in the audio, video, digital, RF and microwave industries, each designed for a specific purpose and application. Much of the development of the smaller connectors that perform well into the GHz and millimeter wave range has been conducted by test equipment measurement companies. One of their considerations is the number of connect-disconnect cycles that a connector pair can withstand while still performing as expected. Why different sizes and frequencies? The frequency range of any connector is limited by the excitation of the first circular waveguide propagation mode in the coaxial structure. Decreasing the diameter of the outer conductor increases the highest usable frequency. Filling the airspace with dielectric lowers the highest frequency and increases losses. The mating process typically changes the geometry of the mating surfaces and resistance loss at those interfaces as well as geometric changes result in variation of impedance and loss. Some RF connectors are sexless (such as the HP/Amphenol APC-7 and the General Radio GR874 and GR900BT). Most connectors have female structures with slotted fingers that introduce a small inductance. The fingers accommodate tolerance variations, but reduce repeatability and may ultimately break after 1000 connections. There are slotless versions of connectors available, but they are, for the most part, relegated to instrument interfaces. Slotless female connectors are very difficult to clean and require very careful connection and disconnection.

  • Coaxial Cable
    ANALOG ELECTRICAL and DIGITAL VIDEO FORMATS and CONNECTORS Analog Electrical Formats/Connectors Component Video Component video is a type of video information that is transmitted or stored as two or more separate signals (as opposed to composite video, such as NTSC or PAL, which is a single signal). Most component video systems are variations of the red, green and blue signals that make up a television image. The simplest type, RGB, consists of the three discrete red, green and blue signals sent down three wires. This type is commonly used in Europe through SCART connectors. Outside Europe, it is generally used for computer monitors, but rarely for TV-type applications. Another type consists of R-Y, B-Y and Y, delivered the same way. This is the signal type that is usually meant when people talk of component video today. Y is the luminance channel, B-Y (also called U or Cb) is the blue component minus the luminance information, and R-Y (also called V or Cr) is the red component minus the luminance information. Variants of this format include YUV, YCbCr, YPbPr and YIQ. In component systems, the synchronization pulses can either be transmitted in one or usually two separate wires, or embedded in the blanking period of one or all of the components. In computing, the common standard is for two extra wires to carry the horizontal and vertical components, whereas in video applications it is more usual to embed the sync signal in the green or Y component. The former is known as sync-on-green.

  • Guide to RF Coaxial Connectors and Cables
    Guide to RF Coaxial Connectors and Cables Given that typical RF systems are comprised of any number of items, e.g. RF generators, amplifiers, attenuators, power meters, couplers, antennas, etc., it is not uncommon that a great deal of thought is given to these “high end” devices while mundane items such as connectors and cables are often treated as an afterthought. With a wide variety of coaxial connectors and cables available for use in the RF and Microwave spectrum not giving these essential components too much thought is a misstep and can result in undesirable system degradation. RF coaxial connectors provide vital RF links in communications, broadcast, EMC testing, commercial and military, as well as test and measurement fields. In this guide, you will learn about the different types of RF Coaxial Connectors and Cables and the various uses for each. Guidance and insight will be provided to assist in choosing connectors best suited to accommodate your specific applications. 1.0 RF Coaxial Connectors The vast array of RF connectors available can be overwhelming, but they are all characterized by just a few key parameters. The most obvious characteristic of a connector is its physical size. Other considerations include power handling and frequency range capabilities. To ensure maximum Find It Fast power transfer, the characteristic impedance of the connector should match the source and load. All of these characteristics, along with connector durability and cost, must be considered for each application.

  • RF and Microwave Coaxial Cable and Connectors
    University of Washington Electrical Engineering & Agilent Technologies RF Laboratory RF and Microwave Coaxial Cable and Connectors Routing of RF and microwave signals with minimum loss and minimum reflections requires controlled impedance lines and connectors. This requires significantly more engineering effort than the simple point-to-point wiring of low frequency electronics. Once off of a printed circuit board, the most common transmission line for RF and microwave signals is the coaxial cable. These are also the standard means for getting signals into and out of various instruments and subassemblies. Connectors for coaxial cables also play a critical role, since they must maintain the controlled impedance of the transmission line while still providing connect and disconnect service. Coaxial Cable The most critical electrical parameters for specifying coaxial cable are: (1) the characteristic impedance Z0, (2) the loss or attenuation per unit length α, and (3) the voltage breakdown strength BV. In addition, there are the mechanical parameters of outside diameter d0, tensile strength, and minimum bend radius. The characteristic impedance of a coaxial cable, or any other transmission line, fundamentally gives the ratio of the electric to magnetic field strength of an electromagnetic wave propagating along the line. For a coaxial cable, the characteristic impedance is related to the inside and outside radii of the dielectric, a and b, respectively, and the permittivity ε and permeability μ of the dielectric material, 1 376.7 Z0 ln b a ln b a . 2 2r The circuit parameters per unit length of the coaxial cable are RS 11 R /m, L ln b a H/m, 22ab 22 GC S/m, F/m.
