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 combination of low cost and high reli-
ability. 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 impedance. A single
external output matching circuit covers the entire 4.9-5.9GHz
band. The external output match allows for load line optimiza-
tion for other applications or optimized performance over nar-
rower bands. It is designed as a drop in replacement for similar
parts in its class. This product is available in a RoHS Compliant
and Green package with matte tin finish, designated by the “Z”
package suffix.
