Title:
TERAHERTZ FREQUENCY BAND ON-CHIP S PARAMETER CALIBRATION METHOD AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/120452
Kind Code:
A1
Abstract:
A terahertz frequency band on-chip S parameter calibration method and a terminal device. The method comprises: acquiring eight error models obtained subsequent to performing preliminary calibration on a terahertz frequency band system (S201); acquiring, according to the eight error models, a first S parameter that is based on a first calibration member, and according to the first S parameter, determining a first mathematical model, wherein the first mathematical model comprises a crosstalk item connected in parallel between probes (S202); acquiring a second S parameter that is based on a second calibration member, and according to the second S parameter, determining a second mathematical model, wherein the second mathematical model comprises a crosstalk item connected in series between the probes (S203); acquiring a third S parameter that is based on a measured member, and according to the third S parameter, determining a third mathematical model (S204); and calculating the Z parameter of the measured member according to the first mathematical model, the second mathematical model, and the third mathematical model, and according to the Z parameter of the measured member, obtaining the S parameter of the measured member (S205). The present method can achieve the accurate measurement of a terahertz frequency band on-chip S parameter.
