Description
The MGS-70008 is a single-pole,
double-throw monolithic GaAs
MMIC switch. The J2 and J3 of the
MGS-70008 are terminated to
ground when “off” (an absorptive
version, the MGS-71008, which
terminates the “off” port in an
internal 50␣ Ω resistor, is also
available). The switches are
sealed in a small, plastic, surfacemount SO-8 package. Switching is
actuated by a -5 V control voltage
per the truth table shown on the
next page. -3.3␣ V operation is also
possible with some reduction in
P
and IP3.

The MGS-70008 is designed for
high volume commercial applications where low insertion loss,
high isolation, and fast switching
speed are required. Its low cost
and high performance make it
suitable for a wide variety of uses
such as digital cellular, spread
spectrum, GPS, and other RF
switching applications. Refer to
applications note AN-G007 for
more application details.
The die is fabricated using HP’s
nominal 0.7␣ µm Schottky-barrier-
gate, gold metallization, and
silicon nitride passivation to
achieve excellent performance,
uniformity, and reliability.
