ETC SZA-2044

Product Description
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 combination of low cost and high reliability.
This product is specifically 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 50Ω nominal RF input
impedance. The external output match and bias adjustability allows load line optimization for other applications or
over narrower bands. It features an output power detector,
on/off power control and high RF overdrive robustness.

VPC1
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.

VPC2
VPC2 is the bias control pin for the stage 2 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 adjacent pins or grounded as
shown in the application circuit.
This is to maintain consistency
with the evaluation board layout shown below. It is recommended to use this layout and
wiring to achieve the specified
performance.
