SGA-2486 Datasheet, PDF (1/4 Pages) List of Unclassifed Manufacturers – DC-5000 MHz, Cascadable SiGe HBT MMIC Amplifier
SGA-2486
Product Description
The SGA-2486 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 higher suppression of intermodulation prod-
ucts. Only 2 DC-blocking capacitors, a bias resistor and an
optional RF choke are required for operation.
SGA-2486 Pb RoHS Compliant
& Green Package
DC-5000 MHz, Cascadable
SiGe HBT MMIC Amplifier
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 no
antimony trioxide nor halogenated fire retardants.
