Datasheet NGA-686 Datasheet (Stanford Microdevices)

Product Description

Stanford Microdevices’ NGA-686 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 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.
