AS219-000

The AS219-000 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.
