The large dynamic multipath broadband calibration source comprises a source signal generation module and an attenuation module; the signal source generation module comprises a phase-locked loop; the source signal generation module is used for generating a source signal of a preset phase and a preset frequency band through the phase-locked ring according to the inputted reference signal and transmitting the source signal to the attenuation module; the attenuation module comprises a switch filtering unit and an attenuation unit; the switch filtering unit is used for filtering harmonic wave and a stray signal in the source signal; the stray signal is the signal, the frequency of which is not in a preset frequency band; and the attenuation unit is used for performing attenuation on the filtered source signal to obtain a first correction signal of a preset amplitude. The large dynamic multipath broadband calibration source, communication device and communication device manufacture method can improve accuracy of a calibration signal.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a large dynamic multi-channel broadband calibration source and communication equipment. Background technique [0002] With the development of communication technology, microwave communication has been widely used due to its advantages of large capacity, good communication quality and long communication distance. In the process of using communication equipment based on microwave communication (such as smart antennas and transceiver equipment), in order to ensure that the communication equipment can accurately send or receive communication signals, it is usually necessary to calibrate the communication equipment through specific calibration signals, Therefore, there is an urgent need for a large dynamic multi-channel broadband calibration source capable of generating the calibration signal. [0003] In the prior art, a large dynamic multi-channel broadband calibration source...
