Features
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)
1. All measurements made in a 50 Ω system, unless otherwise specified.
2. Insertion loss changes by 0.003 dB/°C.
3. Insertion loss state.
