Abstract

The invention provides a single-live-wire radio frequency switch comprising a power supply, a control circuit, a single-chip microcomputer, a radio frequency module, an antenna and a touch key. The power supply is respectively connected with the control circuit and the single-chip microcomputer. The control circuit, the radio frequency module and the touch key are respectively connected with the single-chip microcomputer. The radio frequency module is also connected with the antenna. The radio frequency module works in an FSK modulation mode and comprises a register, and the single-chip microcomputer is connected with the radio frequency module in a communication manner through an SPI interface and sets the register and realizes data receiving and transmitting through the antenna. According to the single-live-wire radio frequency switch, bidirectional communication can be realized so that the signal transmission efficiency can be greatly enhanced, feedback information can be provided and the anti-noise performance is high. With application of the single-live-wire radio frequency switch, FSK modulation can be realized, power consumption can be reduced, the anti-noise performance can be enhanced and the data communication efficiency can be greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of radio frequency switches, in particular to a single live wire radio frequency switch. Background technique [0002] The radio frequency switch belongs to the signal switch used in the cable TV network or the communication field.
