Description
The
MAAPGM0016-DIE
is a 3-stage 5 W 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 reli-
able 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
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 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

before applying positive bias to V

to prevent
damage to amplifier.
