Functional Diagram


Description
The PLN25 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 PLN25 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.
Specifications

Test Conditions : T=25°C, Supply Voltage=+3.0V, 50ohm System, OIP3 measured with two tones at an output power of 0dBm/tone separated by 1MHz.
Application Circuit

- Bypass Capacitors(10nF & 1uF) should be added for bypassing the AC noise
- No matching circuit needed

Evaluation Board Layout (2.3x2.3)

Mounting Instructions
- Use a large ground pad area with many plated through-holes as shown.
- We recommend 1 oz copper minimum.
- Measurement for our datasheet was made on 0.8mm thick FR-4 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.
- All area of GND PAD should be connected to GND
