SZA-3044(Z)
2.7GHz to 3.8GHz 5V 1W
POWER AMPLIFIER
RFMD’s SZA-3044 is a high linearity 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 spe-
cifically designed as a final or driver stage for 802.16 equipment in the 3.3GHz to
3.8GHz bands. It can run from a 3V to 6V supply. Optimized on-chip impedance
matching circuitry provides a 50 nominal RF input impedance. The external out-
put 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. This
product is available in a RoHS Compliant and Green package
with matte tin finish, designated by the “Z” package suffix.

N/C These are unused pins and not wired inside the package. They may be grounded or connected to adjacent pins.
6VPC1
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
10mA.
8VPC2
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
10mA.
10 VDET Output power detector voltage. Load with >10K for best performance
3RF IN RF input pin. This is DC grounded internal to the IC. Do not apply voltage to this pin.

16 VC2 2nd stage collector bias pin. Apply 3.0V to 5.0V to this pin.
18 VC1 1st stage collector bias pin. Apply 3.0V to 5.0V to this pin.
20 VBIAS Active bias network VCC. Apply 3.0V to 5.0V to this pin.
EPAD GND
Exposed area on the bottom side of the package needs to be soldered to the ground plane of the board for optimum ther-
mal and RF performance. Several vias should be located under the EPAD as shown in the recommended land pattern.
