GaAs MMIC SPDT SWITCH
DC - 3 GHz
Features
Ultra Small Package: MSOP8
High Isolation: 50 dB
Positive Control: 0/+3V to 0/+7V
General Description
The HMC194MS8 is a low-cost SPDT switch in
an 8-lead MSOP package for use in applica-
tions which require high isolation between two
RF paths. The device can control signals from
DC to 3 GHz and has been optimized to provide
extremely high isolation with minimal insertion
loss in medium and low power applications. On
chip circuitry allows positive voltage control oper-
ation at very low DC currents with control inputs
compatible with CMOS and most TTL logic fam-
ilies. RF1 and RF2 are reflective opens when
“OFF”.
