Product Description
The SGA-7489 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 ca-
pacitors, 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 whis-
ker formation and is RoHS compliant per EU Direc-
tive 2002/95. This package is also manufactured
with green molding compounds that contain no an-
timony trioxide nor halogenated fire retardants.

Test Conditions:
NOTE: The recommended operating current in the preliminary datasheet was 130mA. Supplemental measurements have since shown
that an operating current of 115mA results in optimal RF performance over temperature. Continued operation at 130mA is reliable,
however, the recommended operating current has been changed to 115mA.
