Preliminary Information
Description
The
MAAPGM0051-DIE
is a 2-stage 1.2 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 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 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 for-
mulation prevents hydrogen poisoning when employed in hermetic
packaging.
Primary Applications
♦
Point-to-Point Radio
♦
Weather Radar
♦

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
