Product Description
SZA-2044 / SZA-2044Z
Sirenza Microdevices’ SZA-2044 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 combi-
nation of low cost and high reliability. This product is specif-
ically designed as a final stage for 802.11b/g and 801.16
equipment in the 2.0-2.7 GHz bands. It can run from a 3V to
5V supply. Optimized on-chip impedance matching circuitry
provides a 50W nominal RF input impedance. The external
output match and bias adjustability allows load line optimi-
zation for other applications or over narrower bands. It fea-
tures an output power detector, on/off power control and
high RF overdrive robustness. This product is available in a
RoHS Compliant and Green package with matte tin finish,
designated by the “Z” package suffix.

VPC1 is the bias control pin for the stage 1 active bias circuit. An external series resistor is required for proper
setting of bias levels. Refer to the evaluation board schematic for resistor value. To prevent potential damage,
do not apply voltage to this pin that is +1V greater than voltage applied to pin 20 (Vbias) unless Vpc supply
current capability is less than 10 mA.

Important Note:
Pins
1,2,4,5,7,9,11,13,15,17,19
are unwired (N/C) inside the
package. Refer to page 2 for
detailed pin descriptions. Some
of these pins are wired to adja-
cent pins or grounded as
shown in the application circuit.
This is to maintain consistency
with the evaluation board lay-
out shown below. It is recom-
mended to use this layout and
wiring to achieve the specified
performance.
Note:
Application circuits are speci-
fied below for 2.0-2.2GHz and
2.3-2.7GHz bands. Only the
output matching circuit compo-
nent values change.
