SGA-7489Z
SGA-7489Z is DC-3000 MHZ SILICON GERMANIUM manufactured by Sirenza Microdevices.
Description
The SGA-7489 is a high performance Si Ge 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 Ro HS pliant per EU Directive 2002/95. This package is also manufactured with green molding pounds that contain no antimony trioxide nor halogenated fire retardants.
