Functional Diagram

Description
The PW450 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 PW450 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.

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.
