SZA-6044 Datasheet, PDF (1/6 Pages) SIRENZA MICRODEVICES – 5.1- 5.9 GHz 1/4 Watt Power Amplifier with Active Bias

Product Description
Sirenza Microdevices’ SZA-6044 is a high linearity Class A
GaAs Heterojunction Bipolar Transistor (HBT) amplifier
housed in a low-cost surface-mountable plastic package.
These HBT amplifiers are fabricated using molecular beam
epitaxial growth technology which produces reliable and
consistent performance from wafer to wafer and lot to lot.
Preliminary
SZA-6044
5.1 – 5.9 GHz ¼ Watt
Power Amplifier with Active Bias
This product is specifically designed as a driver or final
stage amplifier for equipment in the 5.1 - 5.9 GHz band. It
can run from a 3V to 5V supply. Load line optimization for
target band is possible outside the package. Its high lin-
earity makes it an ideal choice for multicarrier and digital
applications.
