The module works in the receiving state by default and amplifies the received signal. When the front-end equipment is detected to transmit external signals, it will instantly switch to the transmitting and amplifying state.

The transmission gain is manually adjustable, which is convenient for compatible wireless devices with different transmission powers.

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.

Compatible with various modulation methods such as LORA and FSK/ASK/OOK/MSK/GFSK.

The default working frequency band 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 .

parameter:

The power supply voltage can be between 3.6V-6.0V.

Remarks: 

The transmission gain when the potentiometer is turned to the end is 11dB.
