AS018R1-01, AS018R1-10

Description

The AS018R1-01 is a GaAs IC FET SPST 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
AS018R1-10 is the gullwing version of this device for
surface mount applications.
