Product Description
The SGA-6286 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 products. Only 2 DC-blocking ca-
pacitors, 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 whis-
ker formation and is RoHS compliant per EU Direc-
tive 2002/95. This package is also manufactured
with green molding compounds that contain no anti-
mony trioxide nor halogenated fire retardants.
