Description
The AS161-86 PHEMT FET IC is a dual transfer switch.
It is ideal for dual band application where T

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. It
requires DC blocks on the RF ports when positive voltage
is used.
