Description
The
MAAPGM0049-Die
is a 3-stage power amplifier with on-chip
bias networks. This product is fully matched to 50 ohms on both
the input and output. It can be used as a power amplifier stage or
as a driver stage in high power applications.
Fabricated using M/A-COM’s repeatable, high performance and
highly reliable GaAs Multifunction Self-Aligned Gate (MSAG
®
)
MESFET Process, each device is 100% RF tested on wafer to
ensure performance compliance.
M/A-COM’s MSAG process features robust silicon-like manufac-
turing 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 manufacturing 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:
Use AuSn (80/20) 1-2 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 pad connections, use either ball or wedge bonds. For best RF performance, use wedge bonds of
shortest length, although ball bonds are also acceptable.
Biasing Note: Must apply negative bias to V
GG
before applying positive bias to V
DD
to prevent
damage to amplifier.
