Description
The AS177-86 is a GaAs FET IC SPDT switch packaged
in a MSOP-10 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.
