AS179-92LF

RF Switches Overview

The AS179-92LF is a pHEMT GaAs FET single-pole double-throw (SPDT) RF switch designed for low insertion loss and minimal DC power consumption. It operates with positive voltage control and supports frequencies from 20 MHz to 4 GHz. Key electrical parameters include a typical P1dB of +30 dBm and IP3 of +43 dBm at 3V. At 0.9 GHz, it achieves an insertion loss of 0.3 dB. The device features a maximum isolation of 23 dB and switching times of 100 ns. It is housed in a compact SC-88 package and functions within a temperature range of -40°C to +85°C.
