Description
M/A-COM's AM42-0055 is a two stage MMIC power am-
plifier in a bolt down ceramic package, allowing easy as-
sembly. The AM42-0055 employs a fully matched chip
with internally decoupled gate and drain bias networks.
The AM42-0055 is designed to operate from a constant cur-
rent drain supply or a constant voltage gate supply. By
varying the bias conditions, the saturated output power per-
formance of this device may be tailored for various applica-
tions.
The AM42-0055 is ideally suited for use as an output stage
in telemetry systems. The AM42-0055 includes internal
supply line bypassing in the package, minimizing the num-
ber of external components required.
M/A-COM's AM42-0055 is fabricated using a mature 0.5-
micron MBE based GaAs MESFET process. The process
features full passivation for increased performance and reli-
ability. This product is 100% RF tested to ensure compli-
ance to performance specifications.

Exceeding any one or a combination of these limits may
cause permanent damage.
3.
Adequate heat sinking and grounding required on flange
base.
4.
Apply -3 volts to pins 5 and 6 (V
GG
), prior to applying +8
volts to pins 1 or 10 (V
DD
). Adjust V
GG
for typical drain cur-
rent.
5.
For optimum IP3 performance, V

bypass capacitors
should be placed within 0.5 inches of the V
DD
leads.
