Preliminary Information
Description
The
MA08509D
is a 3-stage 10 W power amplifier with on-chip bias
networks. This product 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 im-
plant capability enabling power, low-noise, switch and digital FETs on a
single chip, and polyimide scratch protection for ease of use with auto-
mated 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.

Figure 5. Recommended bonding diagram
for pedestal mount.
Support circuitry typical of MMIC characterization fixture for CW testing.
NOTE: Indicated Gate voltage pad (VGG 2) represents the nominal bias
condition. However, the device current can be increased or decreased
as required by bonding to either VGG 1 or VGG 3 (respectively).
Assembly Instructions:
Die attach:
Use AuSn (80/20) 1 mil. preform solder. Limit time @ 310 °C to less
than 7 minutes. Refer to Application Note AN3017 for more detailed information.
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.
