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.
