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