Package: SOT-89
Product Description
Features
RFMD’s SGA9189Z is a high performance transistor designed for operation to
3GHz. With optimal matching at 2GHz, OIP3 = 39dBm, and P1dB = 25.5dBm. This
RF device is based on a silicon germanium heterostructure bipolar transistor (SiGe
HBT) process. The SGA9189Z is cost-effective for applications requiring high linear-
ity even at moderate biasing levels. It is well suited for operation at both 5V and 3V.
The matte tin finish on the 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.
