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)
