Abstract

The invention discloses a method and a device for detecting broadband power. The method comprises the following steps: using a channel selection circuit to perform switch polling on a radio-frequency channel comprising radio-frequency signals to be measured; for each polled radio-frequency channel, according to the scheduled background number, outputting local oscillator signals corresponding to scheduled carriers of the radio-frequency signals to be measured of the radio-frequency channel by a broadband phase-locked loop; and performing power detection on the radio-frequency signals to be measured of the radio-frequency channel by performing scheduled processing on the local oscillator signals and the radio-frequency signals to be measured corresponding to the local oscillator signals. Through the technical scheme, the detection of a multi-band broadband is achieved, the development cost and the link budget are saved, and the precision and the application range of the power detection are effectively improved.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a wideband power detection method and device. Background technique [0002] In the wireless communication system, automatic power calibration is an important function that the base station needs to realize. Among them, automatic calibration is to meet the power of each carrier and the overall Power requirements, at the same time, it also has the function of protecting the power amplifier to prevent the power amplifier from being overexcited and causing the power amplifier to fail. The realization of automatic power calibration is based on the accuracy of the power detection of the forward radio frequency link by the base station system. The power of the link can accurately complete the automatic calibration. [0003] The currently used RF power detection method can effectively meet the needs of single-carrier and multi-carrier power detection, and is compatible with multi-...
