General Description

SAC3209A is a reflective GaAs pHEMT SPST switch die that covers DC to 20 GHz. Isolation stays above 50 dB at 20 GHz, insertion loss is about 1 dB typical and 2 dB at 20 GHz, and return loss is 15 dB.

Control is complementary 0/+5 V logic with a -4.5 V bias, and switching happens in nanoseconds. At 1.21 x 0.65 x 0.1 mm the die is tiny, which makes it easy to drop into broadband on/off paths in radar, ECM and test gear.

Also available as SAC3209AQ3.
