Abstract
A signal transmission device, including a RF processing circuit and a cable connecting circuit including a first choke inductor, a first and second bypass capacitors, and a first coupling capacitor, is provided. One end of the first choke inductor is coupled to a transceiver end of a RF transceiver and the other end is coupled to a first control end of a RF antenna controller. The transceiver end is coupled to a first conductor. The first bypass capacitor is coupled between the other end and a digital ground terminal. The first coupling capacitor is coupled between the digital ground terminal and a RF ground terminal. The second conductor is coupled to the RF ground terminal and a second control terminal of the RF antenna controller at a second connecting end of a RF cable. The second bypass capacitor is coupled between the second control terminal and the digital ground terminal.
