Product Description
The SGA-6486 is a high performance SiGe HBT MMIC Ampli-
fier. 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 op-
eration.

& 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.

Operation of this device beyond any one of these limits may
cause permanent damage. For reliable continous operation,
the device voltage and current must not exceed the maximum
operating values specified in the table on page one.
Bias Conditions should also satisfy the following expression:
IDVD < (TJ - TL) / RTH, j-l
Take into account out of band VSWR presented by devices
such as SAW filters to determine maximum RF input power.
Reflected harmonic levels in saturation are significant.
