Product Description
Features
RFMD’s 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. This product is specifically designed as a driver or final stage amplifier for equip-
ment in the 5.1GHzto5.9GHz band. It can run from a 3Vto5V supply. Load line
optimization for target band is possible outside the package. Its high linearity
makes it an ideal choice for multicarrier and digital applications.
