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
is especially suited for PDC, DCS, PCS,
and 2.4 GHz ISM frequency bands. The
design 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. RF 1
or RF2 is a reflective open when "OFF".
Applications include local oscillator multiplexing in cellular/PCS basestation applications which require high isolation.
