The TU-W1401500 from Arralis is a SPST switch that operates from 92 GHz to 96 GHz. It has a very low insertion loss of 1.6 dB, a very high isolation and return loss of 25 dB. This MMIC switch is fabricated on a robust gallium arsenide 50um substrate. The devices are supplied as die and enable the realisation of a complete 92-96 GHz radar system front end with C/X band inputs and W-band outputs. All bond pads and the die backside are Ti/Au metallised, with a fully passivated amplifier elsewhere.
