The AS172-73 is a PHEMT GaAs IC 4 port switch
designed to combine T/R and antenna changeover
switching capability within one device.This switch has two
controls and is ideal for applications requiring low power
consumption.The AS172-73 has excellent performance
to 2 GHz making it suitable for dual-band handset designs.
