Features:
1) This 433MHz/510MHz/868MHz signal amplifier module is a two-way amplified TDD working mode ,that is the transmit power and receiving sensitivity will be amplified equally.
2) The receiving/sending link has a high degree of isolation, and the receiving link can withstand strong external interference without causing self-excitation of the loop.
3) Compatible with various modulation methods such as LORA and FSK/ASK/OOK/MSK/GFSK.
4) The default working frequency band of 433MHz signal booster is 420MHz-480MHz, and it can be applied to any frequency band between 300MHz-600MHz by adjusting the parameters (bandwidth 60MHz, such as 300MHz-360MHz, 520MHz-580MHz...), if you have such a requirement, please contact us.(Hand-held walkie-talkies cannot use this module to achieve the purpose of extending the transmission range due to their high transmission power)

Basic Parameter:
1. Receiving gain: 11dB±2dB
2. Receiving noise figure: at most 2.0dB
3. Transmission gain: 5dB ? 11dB (±2dB) adjustable
4. Recognition threshold for receiving and sending switching: -2dBm
5. Input power range: 1dBm-25dBm
6. Operating Voltage:The power supply voltage can be between 3.6V-6.0V, maximum transmission power increases as the supply voltage increases.
7. Maximum transmit power:31.5dBm (1.4w) at 3.7V supply voltage; 33.5dBm (2.3w) at 5.0V supply voltage; 34.5dBm (2.8w) at 6.0V supply voltage

Work status indication:
- Receiving : green light is on, blue light is off
- Transmitting : blue light is on, green light is off
- In TDD working mode, the blue light and green light will flash alternately

Working current:
RX status: 10mA (±3mA)
TX status: at most 800mA (3.7v power supply); at most 1000mA(5.0v power supply); at most 1500mA (6.0v power supply)
