Product Description
The SGA-6289 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 no
antimony trioxide nor halogenated fire retardants.

Mounting Instructions
1. Solder the copper pad on the backside of the
device package to the ground plane.
2. Use a large ground pad area with many plated
through-holes as shown.
3. We recommend 1 or 2 ounce copper. Measurements
for this data sheet were made on a 31 mil thick FR-4
board with 1 ounce copper on both sides.

Description
RF input pin. This pin requires the use
of an external DC blocking capacitor
chosen for the frequency of operation.
Connection to ground. For optimum RF
