Product Description
Features
RFMD’s 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 802.11b/g and 802.16 equipment in the 2.0GHz
to 2.7GHz bands. It can run from a 3V to 5V supply. Optimized on-chip impedance
matching circuitry provides a 50 nominal RF input impedance. The external output match and bias adjustability allows load line optimization for other applications
over narrower bands, It features an output power detector,
Optimum Technology on/off power control, and high RF overdrive robustness. This
Matching® Applied
product is available in a ROHS Compliant and Green package
GaAs HBT
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
10mA.
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.

These are unused pins and not wired inside the package. They may be grounded or connected to adjacent pins.
RF input pin. This is DC grounded internal to the IC. Do not apply voltage to this pin.
RF output pin. This is also another connection to the 2nd stage collector.
2nd stage collector bias pin. Apply 3.0V to 5.0V to this pin.
1st stage collector bias pin. Apply 3.0V to 5.0V to this pin.
Active bias network VCC. Apply 3.0V to 5.0V to this pin.
Exposed area on the bottom side of the package needs to be soldered to the ground plane of the board for optimum thermal and RF performance. Several vias should be located under the EPAD as shown in the recommended land pattern.
