AS018R2-01, AS018R2-10
Description
The AS018R2-01 is a GaAs IC FET SPDT reflective
switch.This device is ideal for microstrip applications and
has optimum broadband performance, since all leads are
RF isolated. This product is useful as a modulator and
switch in high reliability and commercial applications.The
AS018R2-10 is the gullwing version of this device for
surface mount applications.
