SGA-4486 Datasheet, PDF (1/4 Pages) SIRENZA MICRODEVICES – DC-4500 MHz, Cascadable SiGe HBT MMIC Amplifier

Product Description
The SGA-4486 is a high performance SiGe HBT MMIC Amplifier. A
Darlington configuration featuring 1 micron emitters provides high
FT and excellent thermal perfomance. The heterojunction in-
creases breakdown voltage and minimizes leakage current be-
tween 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.

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 manu-
factured with green molding compounds that contain no antimony
trioxide nor halogenated fire retardants.
