Description
The TriQuint TGS8422-SCC is a GaAs MMIC SP4T FET switch which operates from
DC to 18 GHz. RF Output arm selection is made through 8 control lines. Control bias
voltages are 0 V and -5 V. Typical insertion loss is 2.5 dB at 9 GHz. Isolation is
typically 37 dB from RF Input to RF Outputs 0, 3 and 47 dB from RF Outputs 1 and 2.
The input and output return loss is typically
13 dB.
The reflective, single-pole, four-throw design utilizes one series and four shunt FETs in
each RF Output arm to produce a broadband, low-loss, high-isolation switch. The
monolithic construction simplifies the assembly process and makes this device useful
for electronic warfare, radar and telecommunication applications.
Bond pad and backside metallization is gold plated for compatibility with eutectic alloy
attachment methods as well as thermocompression and thermosonic wire-bonding
processes. Ground is provided to the circuitry through vias to the backside
metallization.
