TGS2355-SM

Overview

The Qorvo TGS2355-SM is a high-power Single-Pole Double-Throw (SPDT) reflective RF switch designed for demanding applications. It operates within a frequency range of 0.5 GHz to 6.0 GHz and utilizes Qorvo's QGaN25 0.25um GaN on SiC production process. The device typically supports up to 40 W input power handling at control voltages of 0/-40 V. It maintains low insertion loss of 0.8 dB or less, with typical off-isolation of 40 dB. The component is rated for a maximum operating temperature of +150 °C.
