The main function of the 50W RF power amplifier is to amplify the original low power of the 400-470MHZ wireless transmitting device, so that the small device has a large power to make the communication distance farther and clearer. The product integrates a dedicated high-speed program-controlled RF watchdog, which can drive the half-duplex automatic transmission and reception conversion circuit at high speed.It is suitable for all U-segment intercoms and digital transmission equipment on the market, and can perfectly support digital DMR, DPMR, P25, C4FM, SFK frequency hopping. And traditional linear simulation mode. Specification: Input power: 1-5W Output Power : 20W-50W max Transmission frequency: 400-470MHZ Receiving frequency: 50-1000MHz Working mode: half duplex (cannot be received in the transmitting state) Receive loss: -1DB ±0.4 Output power: 25-45W Supply voltage: 10-13.8V Standby current: about 10-30mA Cooling method: housing + heat sink for natural heat dissipation, low noise and quiet Minimum size: 125MM75MM60MM How to connnect: The red wire is connected to the positive pole of the power supply +12V, with the black wire connected to the negative pole of the power supply. The small SMA threaded port is connected to the intercom through the cable, and the large M head is connected to the transmitting antenna.
