The TriQuint TGS8122-SCC is a monolithic single-pole, double-throw (SPDT) GaAs FET switch designed for 8 to 11 GHz. It has low insertion loss, low current consumption, and fast rise/fall time, making it ideal for high-speed switching radar and communication systems.
The TriQuint TGS8122‑SCC is a monolithic single‑pole, double‑throw (SPDT) GaAs FET switch designed for 8 to 11 GHz operation. It offers a typical insertion loss of 0.9 dB, 40 dB isolation at 9 GHz, input and output SWR of 1.5:1 and 1.4:1 respectively, and rise/fall times under 2 ns. The device consumes less than 50 mA with control voltages of –7 V and 0 V.
The switch is supplied in a compact chip package (1.7018 × 0.7112 × 0.152 mm) with gold‑plated bond pads for eutectic, thermocompression, or thermosonic wire‑bonding. It is intended for high‑speed radar and communication systems and includes recommended RF assembly diagrams and mechanical drawings.
