RF Power Amplifier Board Transceiver Circuit PCB Walkie-talkie Kit

RF Power Amplifier Board Transceiver Circuit PCB Walkie-talkie Kit

Product Description:
- The amplifier can uses RA,M Toshiba SU series module and the panel has auto transceiver circuit(not includ the module and radiator).
- The module power voltage has an effect on the transmitting power.Within the working voltage,the lower the voltage,the lower the transmitting power.
- The antenna affects the communication distance and please select the right antenna.
- RF power amplifier board:The PCB panel is peripheral circuit for power module.It can work normally with RA,M series,Toshiba SU series module.It is for 1-5W handheld walkie-talkie.Auto ransceiver circuit,increasing the transmitting power.
