Cascadable SiGe HBT MMIC Amplifier
Description
Product Description
The SGA-3586 is a high performance SiGe HBT MMIC Amplifier.
A Darlington configuration featuring 1 micron emitters provides high FT and excellent thermal perfomance.
The heterojunction increases breakdown voltage and minimizes leakage current between junctions.
Cancellation of emitter junction non-linearities results in high suppression of intermodulation products.
Operation requires only a single positive voltage supply, 2 DC-blocking capacitors, a bias resistor and an RF choke.
The matte tin finish on Sirenza’s lead-free “Z” package is applied using a post annealing process to mitigate tin whisker formation and is RoHS compliant per EU Directive 2002/95.
The package body is manufactured with green molding compounds that contain no antimony trioxide or halogenated fire retardants.
