ON THE MARKET


E-Band Active X5 Multiplier
Model SFA-743843516-12SF-N1 is an E-band X5 active multiplier with center frequency at 79 GHz with minimum +/-5 GHz operational bandwidth. It converts 14.8 to 16.8 GHz/+5 dBm input signal to deliver 74 to 84 GHz frequency band with more than +16 dBm power.
Sage Millimeter

Hand-Flex™ Coaxial Cable
Covering DC to 12.5 GHz, this 8” coaxial cable, 141-8SMNB+, has a bulkhead Female Type-N connector at one end and SMA-Male at the other. Features include low loss, excellent return loss, hand formable, and an 8mm bend radius for tight installations.
Mini-Circuits

Phase Trimmer Series
This new phase trimmer series is designed for RF applications where phase match between two cables is needed for proper system performance. Phase trimmers, offered from DC to 50 GHz, will give an accurate phase adjustment over a specified frequency range.
RLC Electronics

Q: Is there a particular emerging application or technology that intrigues you?

A: We’re doing an increasing amount of GaN MMIC development work. The available performance in terms of both output power and operating frequency is steadily increasing. Although the cost per mm2 of GaN MMICs is still higher than that of alternative solid-state technologies such as GaAs PHEMT, it is falling, and for a given output power level and operating frequency a GaN MMIC will be smaller. GaN is also starting to challenge PA applications previously dominated by vacuum tube devices.

Q: Are you experiencing any effects of the reduction in defense spending or are you anticipating any impact on your business?

A: In the UK there has been something of a pause in defense spending during the past 12 months, as a result of a major reorganization of MoD procurement. This pause is now coming to an end and have seen defense spending rising again. We expect to see a strong emphasis on funding programs that can result in operational cost savings.

Q: Deployment of small cells and distributed antenna systems is increasing rapidly as wireless carriers attempt to provide “broadband wireless data everywhere.” If your company is involved in any portion of the “HetNet” market, please tell us how you feel this market will develop.

A: We’re involved in the development of microwave ICs and subsystems for wireless backhaul. The deployment of small cells is a response to increasing consumer demand for wireless data. The increased interest in backhaul at V-band (the ISM bands around 60GHz) and E-band (the light-licensed spectrum at 71-76GHz and 81-86GHz) where large spectral allocations are available is another means of addressing this demand. We see a huge opportunity in providing innovative solutions for exploiting this spectrum.

Q: China has long been considered the greatest potential global market for many companies in the RF and microwave industry. Do you feel this is still true? Are there other emerging markets that you believe will be lucrative in the next few years?

A: In terms of selling RF and microwave components China will continue to be a large and growing market. There is also a lot of growth potential in India and Russia. A key part of our business offering is selling design services, and selling these into emerging markets is more difficult.

Q: What do you believe will be the greatest challenge for the RF and microwave industry?

A: Keeping pace with the increasing demand for wireless data. People love wireless data and new ways of exploiting it are invented daily. There was a time when operators wondered how they would use up all the data capacity that would be made available by 3G. Since then we’ve learned that if there is wireless data capacity available people will find ways of using it.

Uncertain Times for DefenseIn Defense of DARPA; Lamenting Bell Labs
By Barry Manz

A federal agency like DARPA is a sitting duck for politicians and assorted other critics. It has come up with some truly bizarre programs over years that ultimately either delivered no tangible results, were canceled before they could cause any damage, or attempted to answer questions that nobody was asking or needed answers to.
