Description

The PLN20 is a high performance GaAs p-HEMT LNA(Low Noise Amplifier).
The amplifier features high linear performance, low noise figure,low power consumption and high reliability.
The PLN20 operates from a single voltage supply and no matching circuit needed.The device is a superior performance p-HEMT amplifier that offers high dynamic range in a low cost miniature surface mount type with metal cover.
These PLN series provide the most suitable solutions for LNA in communication systems.

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 datasheet 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. All area of GND PAD should be connected to GND
