Description
M/A-COM's AM42-0054 is a two stage MMIC power ampli-
fier in a bolt down ceramic package, allowing easy assembly.
The AM42-0054 employs a fully matched chip with internally
decoupled gate and drain bias networks. The AM42-0054 is
designed to operate from a constant current drain supply or a
constant voltage gate supply. By varying the bias conditions,
the saturated output power performance of this device may be
tailored for various applications.
The AM42-0054 is ideally suited for use as an output stage in
telemetry systems. The AM42-0054 includes internal supply
line bypassing in the package, minimizing the number of exter-
nal components required.
M/A-COM's AM42-0054 is fabricated using a mature 0.5-
micron MBE based GaAs MESFET process. The process fea-
tures full passivation for increased performance and reliability.
This product is 100% RF tested to ensure compliance to per-
formance specifications.
