Description
The
MAAPGM0028-Die
is a 2-stage 0.5 W power ampli-
fier with on-chip bias networks. This product is fully
matched to 50 ohms on both the input and output. It can
be used as a power amplifier stage or as a driver stage in
high power applications.
Each device is 100% RF tested on wafer to ensure
performance compliance. The part is fabricated using M/
A-COM’s repeatable, high performance and highly reli-
able GaAs Multifunction Self-Aligned Gate (MSAG
®
)
MESFET Process. This process features silicon nitride
passivation and polyimide scratch protection.
