STA-6033 Datasheet, PDF (1/8 Pages) List of Unclassifed Manufacturers – Product Description

Product Description
Sirenza Microdevices’ STA-6033 is a high efficiency class
AB Heterojunction Bipolar Transistor (HBT) amplifier
housed in a low-cost surface-mountable plastic package.
This HBT amplifier is made with InGaP on GaAs device
technology and fabricated with MOCVD for an ideal com-
bination of low cost and high reliability.
Preliminary
STA-6033
4.9 – 5.9 GHz 3.3V Power Amplifier
This product is specifically designed as a final stage for
802.11a equipment in the 4.9 - 5.9 GHz band. It can run
from a 3.0V to 3.6V supply. Optimized on-chip impedance
matching circuitry provides a 50Ω nominal RF input imped-
ance. A single external output matching circuit covers the
entire 4.9-5.9GHz band. The external output match allows
for load line optimization for other applications or opti-
mized performance over narrower bands. It is designed as
a drop in replacement for similar parts in its class.
