1. Independent design and production, full technical support
2. Input power: 20~23dBm, can work even if it is lower than 0.1W
3. Input voltage 5-8.4V, suitable for lithium battery power supply voltage
4. In-depth matching and optimization of the power tube, as far as possible to reach the original manual data
5.8V maximum output 39.2dBm (8.31W)@433MHz, current 1.56A, efficiency 66.5%

This power amplifier can output 39.2dBm (8.31W)@433MHz at 8V maximum, current 1.56A, efficiency 66.5%, very suitable for two lithium battery power supply, can burst out such a large power.

Product parameters:
Input power: 20~23dBm (0.1~0.2W), it can work even if it is lower than 0.1W, the output power will increase with the increase of input power, and finally reach the maximum power point.
Working voltage: 5-8.4V (typical lithium battery power supply voltage)
Working current: 1.6A (Max)
Input impedance: 50 ohm
Output impedance: 50 ohms
Input and output terminals: SMA-k female (external thread inner hole)
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%

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!

Package Included:
1* High frequency power amplifier
