Support circuitry typical of MMIC characterization fixture for CW testing. 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. Specifications subject to change without notice. Customer Service: Tel.
