NGA-386
Product Description
DC-5000 MHz, Cascadable GaAs
HBT MMIC Amplifier
Sirenza Microdevices NGA-386 is a high performance Gallium
Arsenide Heterojunction Bipolar Transistor MMICAmplifierꢀ
Designed with InGaP process technology for improved reliability,
a Darlington configuration is utilized for broadband performance
up to 5 Ghzꢀ The heterojunction increases breakdown voltage
and minimizes leakage current between junctionsꢀ Cancellation
of emitter junction non-linearities results in higher suppres-
sion of intermodulation productsꢀ
