Preliminary
Sirenza Microdevices聮 NGA-286 is a high performance Gallium
Arsenide Heterojunction Bipolar Transistor MMIC Amplifier. De-
signed with InGaP process technology for improved reliability, a
Darlington configuration is utilized for broadband performance up
to 6 Ghz. The heterojunction increases breakdown voltage and
minimizes leakage current between junctions. Cancellation of
emitter junction non-linearities results in higher suppression of
intermodulation products.
