Description
M/A-COM's AM59-0028 is a two-stage MMIC power
amplifier available in a 4 mm FQFP-16 plastic package.
The AM59-0028 has fully matched input and output net-
works. The AM59-0028 is designed to operate from a
constant voltage collector supply. By varying the bias
conditions, the saturated output power performance of
this device may be tailored for various applications.
The AM59-0028 is ideally suited for use as an output
stage in telemetry systems. The AM59-0028 requires
only supply line bypassing, and base resistors, minimiz-
ing the number of external components required.
M/A-COM's AM59-0028 is fabricated using an InGaP HBT
process. The process features full passivation for increased
performance and reliability. This product is 100% RF tested
to ensure compliance to performance specifications.
