Product Description
The SGA-6589 is a high performance SiGe HBT MMIC
Amplifier. A Darlington configuration featuring 1 micron
emitters provides high F
T
and excellent thermal
perfomance. The heterojunction increases breakdown
voltage and minimizes leakage current between junc-
tions. Cancellation of emitter junction non-linearities
results in higher suppression of intermodulation prod-
ucts. Only 2 DC-blocking capacitors, a bias resistor and
an optional RF choke are required for operation.
The matte tin finish on Sirenza’s lead-free package uti-
lizes a post annealing process to mitigate tin whisker
formation and is RoHS compliant per EU Directive 2002/
95. This package is also manufactured with green mold-
ing compounds that contain no antimony trioxide nor
halogenated fire retardants.
