Description
The AS209-321 is a GaAs PHEMT reflective SPDT
switch that has been designed for WLAN TX/RX
applications. This device has been optimized to provide
excellent performance from DC–6 GHz. The AS209-321’s
high frequency, low loss and high linearity make it an
ideal choice for 802.11a, 802.11b and 3.5 GHz fixed
wireless LAN applications.
