SGA-6289
Product Description
The SGA-6289 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 capacitors, a bias resistor and an optional RF
choke are required for operation.
SGA-6289Z Pb RoHS Compliant
& Green Package
DC-4500 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.
