1results about How to "Guaranteed transmit power" patented technology

This invention provides a low-power, ultra-long standby FPV drone image transmission system and its implementation method, comprising: an RF transceiver, a 1-to-2 RF switch, an RF front-end module, and a 1-to-4 RF switch; the signal output terminal of the RF transceiver is electrically connected to the signal input terminal of the 1-to-2 RF switch; the two signal output channels of the 1-to-2 RF switch are respectively electrically connected to the RF input pin of the RF front-end module and the signal input terminal of the 1-to-4 RF switch; the signal output terminal of the RF front-end module is electrically connected to another signal input terminal of the 1-to-4 RF switch; the output terminal of the 1-to-4 RF switch is connected to an antenna. In scenarios where takeoff is not in progress, this invention can shut down the RF amplifier (PA) in the RF front-end module, significantly reducing power consumption and fundamentally solving the heat dissipation problem. Therefore, the image transmission system can operate normally for extended periods without crashing, greatly improving the user experience.
