HMC194MS8
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 applications 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 operation at very low DC currents with control inputs
compatible with CMOS and most TTL logic families. RF1 and RF2 are refl ective opens when
“OFF”.
