Description
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.

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.
