GaAs IC High Isolation Positive Control
SPDT Switch DC–3.0 GHz
Preliminary
AS176-59
Features
I Positive Voltage Control (0/+3 to +5 V)
I High Isolation (50 dB @ 0.9, 1.9 GHz)5
I Low DC Power Consumption
I Ideal for Cellular, GSM, DCS,PCS, 3G and
2.4 GHz ISM Applications
Description
The AS176-59 is a GaAs FET IC SPDT switch packaged
in a MSOP-8 plastic package for low cost, high isolation
commercial applications. Ideal building block for base
station dual band applications where synthesizer isolation
is critical. Use in conjunction with the AS165-59 SPST
switch to meet GSM synthesizer isolation requirements.
