Description
The AS202-000 is a PHEMT GaAs IC SP3T antenna
switch operating in the 800–2500 MHz frequency range.
Switching between the antenna and TX/RXports 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 RXor TX
port, while the other ports have high off isolation. The
AS202-000 is an ideal switch chip for use in antenna switch
and front-end modules.
