General Description
The HMC-SDD112 is a monolithic, GaAs PIN diode
based Single Pole Double Throw (SPDT) MMIC
Switch which exhibits low insertion loss and high
isolation. This all-shunt MMIC SPDT features
on-chip DC blocks and DC bias voltage decoupling
circuitry. All bond pads and the die backside are Ti/
Au metallized and the PIN diode devices are fully
passivated for reliable operation. The HMC-SDD112
GaAs PIN SPDT is compatible with conventional die
attach methods, as well as thermocompression and
thermosonic wirebonding, making it ideal for MCM and
hybrid microcircuit applications. All data shown herein
is measured with the chip in a 50 Ohm environment
and contacted with RF probes.
