Multi-Channel FMCW Radar Transceiver
With four transmit and four receive channels, model SSC-7337331202-1212-B1 is an E-Band FMCW transceiver sub-assembly that operates from 70 to 75 GHz. The transceiver includes a digitally controlled synthesizer, frequency multipliers for transmitters and receivers, a single side-band modulator, a four-way switch for the transmit channels and four I/Q mixers for the receivers. The transmitted power is +2 dBm for each channel and receiver conversion loss is 12 dB. The subsystem requires +6 VDC at 2.3 Amps.

Ultra-Broadband Resistive Power Dividers
HYPERLABS INC. has expanded its line of ultra-broadband resistive power dividers by adding a four-way, 12 dB power divider (HL957X series) and a two-way, two-resistor power splitter (HL948X series). Both additions offer bandwidths from DC to over 67 GHz. The four-way power divider is a lower-cost and smaller-sized option over implementing multiple two-way dividers. The newly released power splitters are suitable for making power ratio measurements as the accuracy of the divided outputs is extremely well tracked. Demos available upon request.

Coaxial Mixer
Mini-Circuits’ model ZMDB-653H-E+ coaxial frequency mixer features RF and LO frequency range of 20 to 65 GHz and IF range of DC to 20 GHz. Well suited for frequency up-/down-conversion in defense radar, communications and test systems, the level 15 (+15 dBm LO power) mixer is 0.56 × 0.56 × 0.34 in. (14.22 × 14.22 × 8.64 mm) with female 1.85 mm connectors. Typical LO-RF isolation is 45 dB with typical conversion loss of 11 dB from 20 to 65 GHz.

Broadband Capacitors
Passive Plus Inc. (PPI) has developed larger broadband capacitors in three larger case sizes: 0402BB, 0603BB and 0805BB. Values available are 10 nF (10,000 pF) and 100 nF (100,000 pF), depending on case size. These capacitors are intended primarily for coupling RF signals or, occasionally, for bypassing them to ground, while blocking DC. The applications for which they are intended require small, surface-mountable devices that provide low RF impedances, i.e., low insertion losses and reflections, across extremely large RF bandwidths and temperatures typically ranging from -55°C to +125°C.

SP3T Switch
Qorvo’s QPC1006 is a single pole, triple throw (SP3T) switch fabricated on Qorvo’s QGaN25 0.25 μm GaN on SiC production process. Operating from 0.15 to 2.8 GHz, the QPC1006 typically supports 50 W input power handling at control voltages of 0/-40 V for both CW and pulsed RF operations. This switch maintains low insertion loss less than 1.0 dB and greater than 30 dB isolation, making it ideal for high-power switching applications across both defense and commercial platforms.
