PHEMT GaAs IC Transfer Switch DC–2 GHz

Features

■ High Linearity (+50 dBm IP3 @ 0.9 GHz)

■ 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.

Electrical Specifications at 25°C (0, +3 V)

Operating Characteristics at 25°C (0, +3 V)
