AS227-321LF PHEMT GaAs IC High-Power SP3T Switch 300 kHz–2 GHz

The AS227-321LF 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.

技术特性
  • Positive low voltage control (0/2.75 V operation)
  • Low insertion loss (0.5 dB typ. @ 1 GHz)
  • High isolation (26 dB typ. @ 1 GHz)
  • Excellent IIP3 (63 dBm @ 2.75 V, 27 dBm/tone)
  • Miniature QFN-12 plastic package
  • PHEMT process
  • Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C
    per JEDEC J-STD-020
