Preliminary
Product Description
NGA-386
Sirenza Microdevices NGA-386 is a high performance Gallium
Arsenide Heterojunction Bipolar Transistor MMIC Amplifier.
Designed with InGaP process technology for improved reliability,
a Darlington configuration is utilized for broadband performance
up to 5 Ghz. The heterojunction increases breakdown voltage
and minimizes leakage current between junctions. Cancellation
of emitter junction non-linearities results in higher suppres-
sion of intermodulation products.
