fixture for C W testing
Assembly:
Chip dimensions: 4.6 mm x 4.6 mm, .003”
thickness.
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 co mpression 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:
1. User must apply negative bias to VGG before
applying positive bias to V
damage to amplifier.
