Description
The
MASWGM0002-Die
is a single pole double throw switch
that is fully matched to 50 ohms on both the input and output.
Fabricated using M/A-COM’s repeatable, high performance
and highly reliable GaAs Multifunction Self-Aligned Gate
(MSAG™) Process, each device is 100% RF tested on wafer
to ensure performance compliance.
M/A-COM’s MSAG™ process features robust silicon-like
manufacturing processes, planar processing of ion implanted
transistors, multiple implant capability enabling power, low-
noise, switch and digital FETs on a single chip, and polyimide
scratch protection for ease of use with automated manufactur-
ing processes. The use of refractory metals and the absence
of platinum in the gate metal formulation prevents hydrogen
poisoning when employed in hermetic packaging.

Assembly Instructions:
Die attach:
Low thermal conductivity silver epoxies are acceptable for die attach of this MMIC. Fol-
low the manufacturer’s instructions. If solder is employed , use AuSn (80/20) 1 mil preform solder.
Limit time @ 300 °C to less than 5 minutes.
Wirebonding:
Bond @ 160 °C using standard ball or thermal compression wedge bond techniques.
For DC and RF pad connections, use either ball or wedge bonds. For best performance, especially
above 10 GHz, wedge bonds of shortest length employed on the RF interconnects is preferred over
ball bonds.
