The SGA-4563 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.
blocking capacitors, a bias resistor and an optional RF choke are
required for operation.

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
