Abstract
The present disclosure provides an electronic device, and a radio-frequency device and a signal transmission component thereof. The signal transmission component is operable in an operating frequency band and applied in a radio frequency device having a signal connector and a radio frequency circuit. The signal transmission component includes a signal transmission line and an electrostatic protection unit. The signal transmission line is disposed between the signal connector and the radio frequency circuit. The electrostatic protection unit is electrically connected to the signal transmission line, and includes a connecting end and a grounding end. An impedance of the electrostatic protection unit is greater than an impedance of the signal transmission line. An electrical length is defined between the connecting end and the grounding end, and the electrical length is less than ¼ of a wavelength corresponding to a lowest operating frequency within the operating frequency band.
