Preliminary
Product Description
Sirenza Microdevices’ SGA-9289 is a high performance transistor
designed for operation to 3 GHz. With optimal matching at 2 GHz,
OIP3=42.5 dBm and P1dB=27.5 dBm. This RF device is based on
a Silicon Germanium Heterostructure Bipolar Transistor (SiGe
HBT) process. The SGA-9289 is cost-effective for applications
requiring high linearity even at moderate biasing levels. It is well
suited for operation at both 5V and 3V.
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.
