Model SSR-9630831560-10-S1 is a compact transceiver designed for millimeter-wave applications from 92 to 100 GHz. It features typical conversion gain of 15 dB when processing -60-dBm received input power across the full frequency range. It provides intermediate-frequency (IF) outputs from DC to 4 GHz and works at a local oscillator (LO) frequency of 16 GHz and power level of +5 dBm. The LO and IF ports are both equipped with female SMA connectors while the RF input port is fitted with WR-12 waveguide and a UG-387/U flange.

The Electromagnetic Field (EMF) Measurement System is now available with isotropic antennas that provide frequency coverage from 9 kHz to 6 GHz. The system, which is compatible with the firm’s various handheld analyzers, including the LMR Master, Spectrum Master, and Cell Master instruments, can detect EMF radiation around wireless networks and their infrastructure equipment to ensure compliance with national emissions standards. The two isotropic antennas employ triaxis sensors with an integrated RF switch, microcontroller, and memory to transmit/receive a spherical radiation pattern so all radiation is measured at the antenna’s geographical position, regardless of the source’s location. A third isotropic antenna is also available, fr use from 700 MHz to 6 GHz.

A series of 8-b programmable phase shifters provide a 360-deg. phase adjustment range in as many as 255 steps with 1.4-deg. increments and high accuracy. The phase shifters are operated by means of transistor-transistor-logic (TTL) control. The phase shifters, which are available in frequency bands from 500 MHz to 37 GHz, are ideal for aerospace and defense radar and electronic-warfare (EW) applications which involve phased-array antennas, phase discriminators, beam forming networks and RF communication systems. Typical phase-shift error spans +/-0.9 to +/-5 deg. with fast switching speed from 30 to 450 ns. The components handle input power levels from +10 to +30 dBm, depending upon model.

For applications within the 9-to-18-GHz frequency range where low noise is important, the model CMD223 balanced low-noise amplifier (LNA) achieves a noise figure of 1.5 dB with better than 22-dB gain across that 9-GHz bandwidth. The GaAs monolithic-microwave-integrated-circuit (MMIC) amplifier is matched to 50Ω and features +13.5-dBm output power at 1-dB compression. It draws 93 mA from a +4-V dc supply. Supplied in die form, the LNA is well suited for point-to-point communications systems, test equipment, and military radios.

Model M1292-02 is a Ka-band microwave power module (MPM) qualified for airborne applications to 50,000 ft. altitude. The millimeter-wave MPM operates from 28.5 to 40.0 GHz with 100 W saturated output power and is well suited for communications systems requiring linear output power and high efficiency in a compact housing. It handles temperatures from -40 to +85°C and runs on a +28-V dc supply. The MPM measures just 9.75 x 8.50 x 1.50 in. and weighs less than 8 lbs. A number of options, including force-air cooling and integrated block upconverter (BUC), will soon be available.
