“Be Very Careful”
By Tom Kurian, President & CEO, Renaissance Electronics Corp. |
“Be very careful” — a mother’s passing comment to her kids as they head outside. The words describe a way of living that is precise, accurate, and deliberate. It involves both forethought and a heightened sense of awareness. I wrote this to build awareness in companies involved in manufacturing and trading products for defense and Sat-Com programs.

Another Sad Moment For the FCC
By Barry Manz
A significant number of rooftop antenna sites owned primarily by wireless carriers exceed FCC public and occupational exposure limits, make it impossible for workers to avoid standing in front of antennas, and are inadequately posted with warnings and barriers. Read More...

Precision Coaxial Connectors Precision Coaxial Connectors
A new line of precision coaxial connectors for semi-rigid and flexible cables is now available. Interfaces include Type N, Type N Right Angle, SMA and TNC connectors that provide excellent VSWR from DC to 18 GHz. Stainless steel passivated construction.
Vida RF
Modular WLAN 802.11ac Test System
A new test system based on the company’s PXI 3000 Series modular instrumentation has been designed to offer measurements over a 160 MHz bandwidth at operating frequencies up to 6 GHz. It is particularly suited for making R&D, design verification, and production measurements on WLAN devices based on the IEEE 802.11ac standard.
Aeroflex Limited
Signal Analyzer Frequency Options
Two new frequency options for the N9000A CXA X-Series signal analyzers provide a low-cost solution for essential microwave signal characterization up to 13.6 and 26.5 GHz. Features include quick measurement of spurs and harmonics due to the CXA’s speed and DANL performance.
Agilent Technologies
Hand-Flex™ Coaxial Cable
The 141-20SM+ Hand-Flex coaxial cable is ideal for interconnection of coaxial components or sub-systems. The construction includes a silver-plated copper clad steel center conductor which maintains the shape after bending. Frequency coverage is DC to 18 GHz.

Duncan Smith
President, Norden Millimeter, Inc.
Q: The importance of sustaining and developing technology has reached a point where states and cities are more actively building relationships with universities and recruiting high-tech companies. However, there continues to be a shortage of engineering graduates, especially those focusing on RF and microwave technology. What would your company do (or is doing) to help promote careers?
A: I think there are several paths to help bolster the number of microwave engineers. Personally I believe the earlier a potential candidate can be influenced the better. This could be through high school and/or college intern programs to educate the students about RF and microwave technology. The other viable approach that comes to mind is to “grow your own.” Take an electrical engineer with a general background and through work teach them the craft of microwave engineering. Really, isn’t this the way most of us old timers learned anyway. School gives you some tools and fundamentals, but the useful in depth knowledge really only comes from on the job training. Currently Norden is growing an RF engineer into a microwave engineer.
Q: For those of you serving the military market, what do you expect 2013 will bring in terms of opportunities in this sector?
A: Unfortunately it’s very hard to tell what 2013 will be like. With the outcome of the recent election it’s not clear if the Republicans and Democrats will actually work together to avoid the $100 billion in forced defense budget cuts at the start of 2013 that are a result of the compromise to raise the federal debt ceiling in 2011. The forced budget cuts would most certainly put a damper on all military acquisitions. If that calamity is avoided there should be opportunities in the signal intelligence arena and also the UAV market.
Q: If your company serves the commercial markets, are you encouraged by any particular emerging application or technology?
A: There is a very exciting emerging application for sensors to detect foreign object debris (FOD) on runways. FOD on runways causes billions of dollars in damage to aircraft yearly. Norden has developed a low cost MMW transceiver designed to be used as part of the FOD detection system.
Q: Last year, we asked what impact the global economic crisis was having on the markets you serve and on how you run your business. What is your current perspective?
A: So far so good. We haven’t seen an obvious impact from the global economic crisis. Our business in Japan is down, our business with the UK is up, our business in general is up. However the future is less certain. A combination of factors have the possibility of creating the “Perfect Storm” from and economic basis. The debt crisis in Europe, possible tax increases and spending cuts in the US, and a bottoming of China’s economy could conspire together to significantly slow the global economy for several years.
Q: What countries or regions do you believe will provide the greatest growth potential for the wireless industry in 2013?
A: I think the strongest growth for the high volume commercial wireless industry will be in China, India, and Latin America. ♦

•Directivity and VSWR Measurements
Return loss and VSWR measurements are complicated by the finite performance of the directional device used to measure the reflected power. The only accurate and convenient way to make return loss measurements is with a well matched high directivity directional coupler or bridge.
