MA08509D
Rev A 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 (MSAGTM) Process, each device is 100% RF tested on wafer to ensure performance compliance. M/A-COM's MSAGTM 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.

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 VGG before applying positive bias to VDD to prevent damage to amplifier.
