SZA-3044Z

SZA3044Z SZA3044Z 2.7GHz to 3.8GHz 5 V 1W 2.7GHz to 3.8GHz 5V 1W POWER AMPLIFIER Package: QFN, 4mmx4mm Product Description Features 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 specifically 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 output match and bias adjustability allows load line optimization for other applications or 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.  GaAs MESFET        InGaP HBT SiGe BiCMOS  Si BiCMOS  SiGe HBT GaAs pHEMT P1dB =31dBm at 5V 802.11a 54Mb/s 2.5% EVM Performance POUT =24dBm, VCC=5V, 340mA, PAE 14.5% POUT =25dBm, VCC=6V, 365mA, PAE 14.5% On-Chip Output Power Detector Robust - Survives RF Input Power=+15dBm On Chip ESD Protection Class 2 (2000V) Power Up/Down Control 10K for best performance 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. Package Drawing Dimensions in millimeters (inches) Refer to drawing posted at www.rfmd.com for tolerances. Part Symbolization The part will be symbolized with an “SZA-3044” for Sn/Pb plating or “SZA-3044Z” for RoHS green compliant product. Marking designator will be on the top surface of the package.
