ALPHA AS160-86

Preliminary
PHEMT GaAs IC Transmit/Dual Receive
Switch With Diversity Antennas 0.5–2 GHz
AS160-86
Features
MSOP-10
■ Five RF Ports
PIN 10
■ Transmit to Either of Two Antennas
■ Receive From Either of Two Antennas
■ Differential Biasing for High Linearity
Description
The AS160-86 is a PHEMT GaAs IC transfer and SPDT
switch. This switch is ideal for dual band applications where
TX/RX diversity is required. The switch has 4 control lines
that may be positive, negative or a combination of both
(differential biasing). This switch is designed for
commercial wireless applications such as GSM, DCS and
PCS systems.
