Description

technical field

[0001] The invention relates to a signal transmission device, in particular to a radio remote controller. Background technique

[0002] Radio technology is a technology that uses oscillators to generate radio waves to propagate signals. The main working principle of radio technology is that firstly, changes in the strength of the current in the conductor will generate radio waves. When radio waves propagate through space and reach the signal receiving end, radio waves The electromagnetic field change caused by the radio wave will generate an electromagnetic current in the conductor, and finally the original information is extracted from the current change by demodulating the electromagnetic wave, and the purpose of transmitting the radio signal is achieved.

[0003] The initial development of radio from electron tube to transistor, and transition to integrated circuit, and then experienced the process from short wave to ultrashort wave, and then to microw...
