1 PW8 Features Applications Functional Diagram - MHz 9 db Gain at 7MHz +.8 dbm PdB + dbm Output IP Single Voltage Supply Lead-free / Green / RoHS- compliant SOT-89 Package Description IF Amplifier VHF/UHF Transmission Mobile Infrastructure RFID/ Fixed Wireless Function Pin No. RF IN RF OUT / Bias Ground, The PW8 is a high performance InGaP HBT MMIC Amplifier and consists of Darlington pair amplifiers with temperature compensation. The amplifier features high linear performance, high reliability as an IF amplifier and provides stable current variation over temperature. The PW8 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 IF amplifier that offers high dynamic range in a low cost surface-mountable plastic SOT-89 packages.

Use a large ground pad area with many plated through-holes as shown.. We recommend oz copper minimum.. Measurement for our data sheet was made on.8mm thick FR- Board.. Add as much copper as possible to inner and outer layers near the part to ensure optimal thermal performance.. RF trace width depends on the board material and construction. 6. Add mounting screws near the part to fasten the board to a heatsink.
