Features

16.4 dB Gain at 0.9GHz +20 dBm P1dB +38 dBm Output IP3 Single Voltage Supply Lead-free / Green / RoHS- compliant SOT-89 Package

Applications

Cellular, PCS, GSM, GPRS, WCDMA, WiBro W-LAN / DMB / ISM CATV / DBS RFID / Fixed Wireless Functional Diagram Function Pin No. RF IN 1 RF OUT / Bias 3 Ground 2,4 The PW570 is a high performance InGaP HBT MMIC Amplifier and consists of Darlington pair amplifiers. The amplifier features high linear performance, wideband operation, and high reliability. The PW570 operates from a single voltage supply and requires only two DC-blocking capacitors, a bias resistor and an inductor for operation. The device is a general purpose buffer amplifier that offers high dynamic range in a low cost surface-mountable plastic SOT-89 packages.

MSL (Moisture Sensitive Level) Rating : Level 3 at +260°C Convection reflow, J-STD-020 Mounting Instructions 1. Use a large ground pad area with many plated through-holes as shown. 2. We recommend 1 oz copper minimum. 3. Measurement for our data sheet was made on 0.8mm thick FR-4 Board. 4. Add as much copper as possible to inner and outer layers near the part to ensure optimal thermal performance. 5. RF trace width depends on the board material and construction. 6. Add mounting screws near the part to fasten the board to a heatsink. Product Code Lot Number
