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.
