Description
The AS202-321 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 an Rx or Tx port, while the other ports have
high attenuation.
