A
= +25 °C, with -5/+5V Control, 50 Ohm System
Typical Applications
This HMC-SDD112 is ideal for:
• FCC E-Band Communication Systems
• Short-Haul / High Capacity Radios
• Automotive Radar
• Test & Measurement Equipment
• SATCOM
• Sensors
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 en-
vironment and contacted with RF probes.
