Description

The AS173-73 is a PHEMT GaAs FET IC high linearity

SPDT switch in a SOT-6 plastic package. This switch has

been designed for use where extremely high linearity, low

insertion loss and ultra miniature package size are

required. It can be controlled with positive, negative or a

combination

implementations include antenna changeover, T/R and

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

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

1. All measurements made in a 50 Ω system, unless otherwise specified.

2. DC = 300 kHz.

3. Insertion loss changes by 0.003 dB/°C.
