Description

technical field [0001] The present invention relates to the communication field, and in particular, to a radio frequency signal generation and radio frequency power detection device, a method for power detection using a radio frequency signal generation and radio frequency power detection device, and a radio frequency signal generation and radio frequency power detection device for radio frequency signal generation. Method for output power self-calibration. Background technique [0002] In the production process of radio frequency equipment, it is generally necessary to use radio frequency instruments to test the performance of the product. For example, when testing indicators such as board gain, output power, and receiving sensitivity of the transmitting and receiving boards of radio frequency equipment, radio frequency instruments such as signal sources and power meters (or spectrum analyzers) are required. [0003] The RF instrument can accurately measure various indicat...
