Product Description
The SGA-6389 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 junctions. Cancellation of emitter junction non-
linearities results in higher suppression of intermodulation
products. 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 utilizes 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 molding compounds that contain
