The SGA-4363 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.
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. Use a large ground pad area near device pins 1, 2,
4, and 5 with many plated through-holes as shown.
2. 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. Use via holes for
best performance to reduce lead
