Product Description
Sirenza Microdevices’ SZA-5044 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
SZA-5044
4.9 – 5.9 GHz 5V Power Amplifier
This product is specifically designed as a final stage for
802.11a equipment in the 4.9 - 5.9 GHz band for a 5V sup-
ply. Optimized on-chip impedance matching circuitry pro-
vides a 50Ω nominal RF input impedance. A single
external output matching circuit covers the entire 4.9-
5.9GHz band simultaneously. The external output match
allows for load line optimization for other applications or
optimized performance over narrower bands.
