RF Amplifier Board Transceiver Circuit Radio Frequency Walkie Talkie PCB Module for U V Analog Signa

Feature: 1. Usage Requirement: PCB board for the power module peripheral circuitry, with for RA M series, for Toshiba S series modules to work properly. 2. Professional: The RF amplifier board is mainly developed for 1‑5W handheld walkie talkie, with automatic transceiver conversion circuit. 3. Clear Voice: Increase the transmit power of the walkie talkie to have the power of the car radio, and the talking range is farther and the voice is clearer. 4. Heat Sink Preparation: Before installation, you should prepare a heat sink with an area larger than the PCB board, the thickness is recommended to use more than 25mm/0.98in. 5. Installation: RA series module must detach all pins from the PCB board before debugging, wait for the voltage adjustment before welding all pins.
