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
T_X/R_X 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 R_X or T_X port, while the other ports have
high attenuation.
