Abstract

The present application relates to the field of communication technology, and discloses a method for adjusting the transmission power of an antenna, including: acquiring a first clock signal; the first clock signal is used to trigger the antenna to perform signal transmission; adjusting the voltage amplitude of the first clock signal; The antenna transmit power is adjusted according to the adjusted first clock signal. By adjusting the voltage amplitude of the clock signal used to trigger the antenna for signal transmission, the effect of adjusting the wireless transmission power is realized. Compared with the existing method of adjusting the antenna transmission power, the power adjustment can be realized without changing the number of parallel connections of the power tubes ,More convenient. The application also discloses a device and communication equipment for adjusting the transmission power of the antenna.

Description

technical field [0001] The present application relates to the technical field of wireless communication, for example, to a method and device for adjusting antenna transmission power, and communication equipment. Background technique [0002] At present, wireless communication devices are more and more widely used in daily life. The antennas of wireless communication devices have different coupling coefficients at different distances, and the communication between devices is very dependent on the field strength and transmission power of the electromagnetic field, so adjusting the transmission power of wireless communication devices can effectively adjust the communication distance and quality. The power amplifier of traditional wireless communication equipment adjusts the transmission power of the antenna by changing the number of parallel connections of MOS tubes (metal oxide semiconductors, metal-oxide-semiconductor field effect transistors). When the transmission power nee...
