【Abstract】 Coupling attenuation is measured by reverberation chamber method. The reverberation chamber method greatly increased the measurement upper frequency. Coupling attenuation is converted to mixed-mode S-parameter by combining mixed-mode S-parameters theory with reverberation chamber method. The problem of high frequency differential mode signal measurement is solved. The measurement of 4-port VNA is combined with computer control, and the mixed-mode S-parameters are obtained by calculation. By comparison with the results absorbing clamp method, it is concluded the reverberation chamber method is feasible.更多还原
