GaAs MMIC SPST Switch DC~20GHz

General Description

SAC3209A is a general purpose broadband high isolation reflective GaAs pHEMT SPST switch in bare die. The switch offers over 50dB isolation and less than 2dB
insertion loss over operation frequency. Its fast switching and compact size make this reflective SPST ideal for many critical applications. The switch operates using
complementary positive control voltage logic lines of 0/+5V and the bias voltage is -4.5V.
The chip offers full passivation for increased reliability and moisture protection.
This amplifier is the perfect alternative to higher cost hybrid amplifiers.
