Figure 5. Recommended bonding diagram for pedestal
mount. Support circuitry typical of MMIC characterization
fixture for CW 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 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:
1. User must apply negative bias to V
GG
before
applying positive bias to V
DD
to prevent
damage to amplifier.
