DATA SHEET
AS227-321: PHEMT GaAs IC High Power
SP3T Switch DC–2 GHz
Features
● Positive low voltage control (0/2.75 V operation)
● Low insertion loss (< 0.5 dB @ 1 GHz)
● High isolation (> 25 dB @ 1 GHz)
● Excellent IIP3 (63 dBm @ 2.75 V, 27 dBm/tone)
● Miniature QFN-12 plastic package
● PHEMT process
Description
The AS227-321 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.
