MTT-S IMS 2015 - Wearables Take Flight
The most prevalent theme throughout IMS 2015 in Phoenix, AZ was the future development of the Internet of Things (IoT), including applications such as wearable technology, connected medical devices, vehicle-to-vehicle communications and machine-to-machine communications. The opening and closing plenary speakers addressed medical applications, and a wearable display area was part of the exhibition floor. This included a mind controlled car race and demos of a pet tracking device and wireless breathalyzer.
Another hot topic at IMS was 5G communications. Test and measurement and semiconductor companies shared their perspectives in a special MicroApps panel session organized by Microwave Journal. There were also a growing number of talks and products addressing the NewSpace market as commercial companies are starting to participate in the space market. The space industry is demanding lower cost, lighter weight and smaller form factor antennas and components. The same demands will be made on high frequency products for the growing commercial UAV market, which is expected to grow quickly.
The Microwave Journal editors were walking the exhibition floor meeting with companies and learning about their new products. Here’s a summary of what we saw:

With the increased interest in 60 GHz Communication Links, Farran Technology has developed a new range of frequency extension products designed for this growing mm-wave test area. The Frequency Communication Extender (FCE) range is designed to work with an arbitrary waveform generator in the up-conversion chain and a suitable oscilloscope at the receiver side. The system takes external LO to allow for the RF signal to be swept across the full 57 – 65 GHz band of interest for 60 GHz communication systems. The system is designed to produce output P1 dB of +20 dBm from the transmitter and a receiver noise figure of less than 10 dB (~ 7dB typical). Applications include antenna testing, 60 GHz backhaul equipment testing and 60 GHz system chip measurements.
Holzworth recently introduced the HSM18001B RF synthesizer module that is a broadband signal source (10 MHz to 20 GHz, 0.001 Hz minimum step size) providing excellent spectral purity from sub-VHF through Ku-Band. Typical phase noise at 18 GHz is -106 dBc/Hz at 10 kHz offset. The HSM18001B has an adjustable output power dynamic range covering -20 to +20 dBm in 0.01 dB steps as well as an integrated pulse modulation function with rise and fall times as fast as 10 ns. While performance is crucial for many applications, reliability is extremely valuable if not critical for most. This compact, CW source has a field proven mean time between failures (MTBF) of greater than 240,000 hours, making it optimal for both commercial and defense applications.
Ingun showcased its high current test probes, including the HSS range, which depending on the series can transmit 400 A of continuous current. For secure transmission of high currents, the plunger of the high current test probes is divided into two parts. During the stroke motion both plunger parts are deflected away from each other in a radial direction. This causes the plunger parts to press against the barrel and the internal resistance is reduced. Using this principle, high current transfers with minimal heat generation are possible. The test probes are used in many industries and applications such as measurement and testing in production as well as mounted contact elements. A further application is precise measurements, where test probes with the lowest possible internal resistance are needed.
