Product Description
Features
RFMD’s 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 combination of low cost and high reliability. This product is specifically designed as a final or driver stage for 802.11a equipment in the
4.9GHzto5.9GHz band for a 5V supply. Optimized on-chip impedance matching circuitry provides a 50Ω nominal RF input impedance. A single external output matching circuit covers the entire 4.9GHzto5.9GHz band simultaneously. The external
output match allows for load line optimization for other appliOptimum Technology cations or optimized performance over narrower bands. 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.

Description
Pins are not used. May be grounded, left open, or connected to adjacent pin.
VPC1 is the bias control pin for the stage 1 active bias circuit and can be run from 2.9Vto5V control. An external series
resistor is required for proper setting of bias levels depending on control voltage. 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 and can be run from 2.9Vto5V control. An external series
resistor is required for proper setting of bias levels depending on control voltage. 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.
VPC3 is the bias control pin for the stage 3 active bias circuit and can be run from 2.9Vto5V control. An external series
resistor is required for proper setting of bias levels depending on control voltage. 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.
Output power detector voltage. Load with 10Kto100K Ω to ground for best performance.
RF input pins. This is DC grounded internal to the IC. Do not apply voltage to this pin. All three pins must be used for
proper operation.
RF output pin. This is also another connection to the 3rd stage collector
3rd stage collector bias pin. Apply 5V to this pin.
2nd stage collector bias pin. Apply 5V to this pin.
1st stage collector bias pin. Apply 5V to this pin.
Active bias network VCC. Apply 5V 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 (page 5).

Notes: Pins 1, 3, 5, 9, 11, 15, and 17 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 consistence with
the evaluation board layout shown below. It is recommended to use this layout and wiring to achieve the specified performance.
To prevent potential damage, do not apply voltage to the VPC pin that is +1V greater than voltage applied to pin 20 (VBIAS/VCC)
unless VPC supply current capability is less than 10mA.
