433MHz 8W Power Amplifier Board RF HF High Frequency Amplifiers Digital Power Amplificador
This power amplifier can output 39.2dBm (8.31W)@433MHz at 8V maximum, current 1.56A, efficiency 66.5%, very suitable for two lithium power supply, can burst out such a large power. The development team has done in-depth matching and optimization of this power tube, welcome to compare and test.
Working frequency: 400-460MHz
Maximum output power (P1dB):
8.32W (39.2dBm)@8V 1.56A efficiency 66.6%
6.76W (38.3dBm)@7V 1.43A efficiency 67.5%
5.12W (37.1dBm)@6V 1.26A efficiency 67.7%
For details, please see the test picture at the bottom of the page
Please note: Due to the large output power, do not connect the antenna directly to the output port of the power amplifier!
Please use a 50 ohm coaxial cable of no less than 2 meters to connect to the antenna to prevent strong signals from interfering with the normal operation of the power amplifier!
Input power: 20~23dBm (0.1~0.2W), it can work under 0.1W, the output power will increase with the increase of input power, and finally reach the maximum power point.
