Description
The TriQuint TGS8122-SCC is a monolithic single-pole, double-throw (SPDT) GaAs
FET switch designed for 8 to 11 GHz. This device has low insertion loss, low current
consumption of less than 50 mA with control voltages of -7 V and 0 V, and rise and fall
times are less than 2 ns. Ground is provided to the circuitry through vias to the
backside metallization.
This switch is ideal for use in high-speed switching radar and communication systems.
Bond pad and backside metallization is gold plated for compatibility with eutectic alloy
attachment methods as well as the thermocompression and thermosonic wire-bonding
processes.
The TGS8122-SCC is supplied in chip form and is readily assembled using automated
equipment.
