Calibration and group testing system for radio frequency units and method therefor

A calibration and group measurement system for radio frequency (RF) units, comprising:

• a control device;
• a signal source device, connected with the control device, the signal source device outputting a microwave signal source according to signal source information emitted by the control device;
• a test platform, connected with the control device and the signal source device, the test platform being provided to place N RF units and performing M times of stimulations on the RF units, wherein during each of the stimulations, the test platform transforms the microwave signal source into N random microwave signals, the RF units respectively output the N random microwave signals, and the N random microwave signals are superimposed to form a measurement signal;
• and
• a measurement device, connected with the control device, wherein the measurement device is configured to receive M times of the measurement signal to generate M pieces of measurement information respectively, and transmit the M pieces of measurement information to the control device;
• wherein the control device is configured to perform signal solution to obtain solution results according to the M times of the M pieces of measurement information and the M times of the N random microwave signals, and perform iterative calculation and convergence calculation on the solution results to obtain amplitude information and phase difference information of the RF units;
• wherein the N and the M are positive integers.
