Fiscal 2010 Annual Report
Fiscal 2010 Annual Report A V I E L Electronics Chief Executive Officer’s Letter to Stockholders September 22, 2011 Fellow Stockholders: Fiscal Year 2010, which ended on October 31, 2010, was a year in which RF Industries achieved its eighteenth consecutive year of profitability and rebounded from a sales decline in Fiscal 2009 that was the result of the recession and the industry-wide slowdown in wireless infrastructure spending. The improvements in our operations in 2010, and the strengthening of our balance sheet in Fiscal 2010 enabled us to once again focus on our longer term goals of growth and acquisitions. Despite the general economic uncertainty in 2010, the improvement of RF Industries’ operations in Fiscal 2010 and the strength of its October 31, 2010 balance sheet provided us with the security and comfort to (i) expand our operations to the East Coast through the purchase Cables Unlimited, Inc., our new fiber optics and harness assembly subsidiary that we purchased in June 2011, and (ii) significantly increase the dividends that we are distributing to you stockholders. Fiscal 2010 Results For the fiscal year ended October 31, 2010, sales were $16,322,000, compared to sales of $14,213,000 in fiscal 2009. Operating income was $2,004,000 compared to $906,000 in 2009, and net income after taxes was $1,220,000, or $0.38 per diluted share, compared to net income of $656,000, or $0.20 per diluted share for fiscal 2009. Sales at the RF Connector and Cable Assembly segment, our most profitable business segment, increased 16% to $14,094,000 from $12,154,000 in fiscal 2009. -
NEW PRODUCT RELEASE Universal Cable Test Kit for Wi-Fi and Broadband Applications
Division of RF Industries NEW PRODUCT RELEASE Universal Cable Test Kit for Wi-Fi and Broadband Applications Wireless, Wi-Fi and Broadband infrastructure installation requires cables for RF and data throughput. Testing these cable assemblies in the field can be difficult with the variety of unique connectors available today as well as the popular reverse polarity styles. The RFA-4028-WIFI kit by RF Connectors, a division of RF Industries, simplifies the task. The kit contains a Unidapt RF Cable tester (RFA-4018-20) with an assortment of 30 universal adapters, including male and female MMCX, N, Reverse Polarity TNC, Reverse Polarity SMA, TNC, BNC and SMA connector interfaces. By joining two adapters using a universal center included in the kit, coaxial adapters can be made with any combination of these interfaces. The RFA-4018-20 coaxial cable tester is a solid-state continuity checker that measures for opens and shorts. The LED display indicates continuity for the shield and center conductor, as well as check for shorting across conductor paths. An additional continuity tester is included for testing CAT5/5E/6 straight through or crossover RJ-45, UTP, 10Base-T, 100Base-T, 1000Base-T EIA/TIA 568A/568/B network cables. The LED display on the tester identifies the cable pairs and indicates a correctly wired cable. It will also indentify crossed pairs or miss-wired pairs. The kit is housed in a foam-lined impact resistant plastic case. Available from RF Connectors distributors throughout the US, Canada and Mexico. For additional information call 800-233-1728 or 858-549-6340. -

Wifi Interface Identifier from RF Industries
WiFi Interface Identifier from RF Industries Today’s wireless market has exposed us to many new, and some familiar connectors. The wide range of antennas, access points, routers, WLAN’s, cellular devices, PCMCIA cards, Bluetooth, and wireless broadband equipment now available to meet Wi-Fi IEEE802.11a/b/g requirements can sometimes seem bewildering. What are the input and output connectors used with Wi-Fi ® certified products which include: access points, gateways, residential gateways, PC cards, PCI cards, PCMCIA cards, UB devices, wireless print servers, WLAN enabled computers, PC peripherals, antennas, LANs and Internet access devices? Many of these connectors are not easily recognizable. We will try to give you a little background on the common Wi-Fi connectors and some tips to help you identify them. In addition to specialized interfaces which are relatively new to the coaxial market, such as DMX, MC Card, MHF, there are variations on standard RF connectors styles which satisfy FCC Part 15 and 802.11 requirements. The most popular method used to achieve compliance has been to create reverse polarity, or gender, versions of BNC, MCX, MMCX, N, SMA, SMB, SSMB and TNC connectors. You will also find reverse, or left- handed thread versions of N, SMA and TNC connectors. QMA QMA connectors are quick disconnecting versions of SMA connectors; they snap on and off rather than mate by turning threads. QMA’s couple in two seconds rather than twenty, but more importantly, they can be rotated 360 degrees after they are mated, optimizing the flexibility of installations and durability of jumpers. The QMA coupling mechanism creates a 360-degree butt joint that is maintained even with rotation, resulting in low RF leakage. -
Variable Capacitors in RF Circuits
Source: Secrets of RF Circuit Design 1 CHAPTER Introduction to RF electronics Radio-frequency (RF) electronics differ from other electronics because the higher frequencies make some circuit operation a little hard to understand. Stray capacitance and stray inductance afflict these circuits. Stray capacitance is the capacitance that exists between conductors of the circuit, between conductors or components and ground, or between components. Stray inductance is the normal in- ductance of the conductors that connect components, as well as internal component inductances. These stray parameters are not usually important at dc and low ac frequencies, but as the frequency increases, they become a much larger proportion of the total. In some older very high frequency (VHF) TV tuners and VHF communi- cations receiver front ends, the stray capacitances were sufficiently large to tune the circuits, so no actual discrete tuning capacitors were needed. Also, skin effect exists at RF. The term skin effect refers to the fact that ac flows only on the outside portion of the conductor, while dc flows through the entire con- ductor. As frequency increases, skin effect produces a smaller zone of conduction and a correspondingly higher value of ac resistance compared with dc resistance. Another problem with RF circuits is that the signals find it easier to radiate both from the circuit and within the circuit. Thus, coupling effects between elements of the circuit, between the circuit and its environment, and from the environment to the circuit become a lot more critical at RF. Interference and other strange effects are found at RF that are missing in dc circuits and are negligible in most low- frequency ac circuits. -
