Description

The PW117 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 PW117 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.

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.
