Description
The AS165-59 SPST IC FET switch is absorptive on the
input. The switch features high isolation and low insertion
loss. Ideal building block for base station applications
where synthesizer isolation is critical. Use in conjunction
with the AS164-80 SPDT switch to meet GSM synthesizer
switch isolation requirements.
