Product Description
Stanford Microdevices NGA-689 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 suppression
of intermodulation products.
