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.

FEATUREs
● Positive low voltage control (0/2.75 V operation)
● Low insertion loss (< 0.8 dB @ 2 GHz)
● High isolation (25 dB at 1 and 2 GHz)
● Excellent harmonics performance
   (-65 dBc @ 2.75 V 1 GHz, PIN = 34 dBm)
● Miniature QFN-12 plastic package
● PHEMT process
● Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C per JEDEC J-STD-020
