AS219-321LF General Description


PHEMT GaAs IC High Linearity 3 V T/R SP3T Switch 0.12.5 GHz


The AS219-321 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 a TX port, while the other RX ports have high attenuation.

AS219-321LF Maximum Ratings

  • +2.6 to +5 V Linear Operation
  • Harmonics H2, H3 > 70 dBc @ PIN = 34.5 dBm
  • Low TX Insertion Loss (0.35 dB @ 0.9 GHz)
  • High RX Isolation (25 dB @ 0.9 GHz)
  • Miniature MLP-12 Plastic Package
