PHEMT GaAs IC Transfer Switch DC–2 GHz
Features
■ High Linearity (+50 dBm IP3 @ 0.9 GHz)
@3V
■ Low Insertion Loss (0.4 dB @ 0.9 GHz)
■ Isolation (20 dB @ 0.9 GHz)
■ Simultaneous T/R Switching
Description
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.
