Preliminary
Product Description
Sirenza Microdevices' STA-6033 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 802.11a equipment in the 4.9 - 5.9 GHz band. It can run from a 3.0V to 3.6V supply. Optimized on-chip impedance matching circuitry provides a 50 nominal RF input impedance. A single external output matching circuit covers the entire 4.9-5.9GHz band. The external output match allows for load line optimization for other applications or optimized performance over narrower bands. It is designed as a drop in replacement for similar parts in its class.

Pin Out Description
Pin # 1,4,9,12,13 5 Function N/C VPC1 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. 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 16 (Vbias) unless Vpc supply current capability is less than 10 mA. 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 16 (Vbias) unless Vpc supply current capability is less than 10 mA. VPC3 is the control pin for the stage 3 active bias circuits. 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 16 (Vbias) unless Vpc supply current capability is less than 10 mA. Ouput power detector voltage. Load with 10K-100K ohms 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 3.0V to 3.6V to this pin. 2nd stage collector bias pin. Apply 3.0V to 3.6V to this pin. 1st stage collector bias pin and active bias network VCC. Apply 3.0V to 3.6V 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).

4.9 - 5.9 GHz Evaluation Board Schematic For Vcc = Vpc = V+ = 3.3V Supply
Notes: Pins 1,4,9,12,13 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. To prevent potential damage, do not apply voltage to the Vpc pin that is +1V greater than voltage applied to pin 16 (Vbias/Vcc) unless Vpc supply current capability is less than 10 mA. See table below for other Vpc logic level resistor values. See AN-064 if using other than Vcc=3.3V for Vpc resistors values.
