AS202-321

PRELIMINARY DATA SHEET AS202-321, AS202-321LF: PHEMT GaAs IC High-Power SP3T Switch LF–2 GHz 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 ● Functional Block Diagram ANT V1 V3 RF1 RF3 RF2 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. NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.
