Qorvo's TGS8422-SCC is a GaAs MMIC single-pole, four-throw (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 and 3 and 47 dB to 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 (EW), 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.
