Description
The AS018M2-01 is a GaAs IC FET SPDT non-reflective
switch. This device is ideal for microstrip applications and
has optimum performance at higher frequencies
(410 GHz), since all leads are RF isolated. This product
is useful as a modulator and switch in high reliability and
commercial applications. The AS018M2-10 is the gullwing
version of this device for surface mount applications.
