SGA-6486
Product Description
RoHS Compliant
& Green Package
Pb
SGA-6486Z
DC-4500 MHz, Cascadable
SiGe HBT MMIC Amplifier
The SGA-6486 is a high performance SiGe HBT MMIC Ampli-
fier. A Darlington configuration featuring 1 micron emitters
provides high F and excellent thermal perfomance. The
T
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 op-
eration.
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.
