PHEMT GaAs IC High Linearity 3 V T/R SP3T Switch 0.12.5 GHz

The AS219-321LF is a PHEMT GaAs IC SP3T antenna switch operating in the 900 MHz and 1800 MHz frequency bands. Switching between the antenna and TX/RX ports is accomplished with 3 control inputs. When the control inputs are driven with the appropriate voltages, a low insertion loss path is provided from an antenna port to a TX port, while the other RX ports have high attenuation.
