|
| () |
| Abstract: |
| Based on the principle of micro frequency changing phase shift, a new approach for RF phase calibration is proposed. In this approach, fixed electrical length is adopted and through micro changing signal frequency to realize shifting, the RF phase is calibrated. Theoretical analysis and experimental result show that this approach can improve the calibrating accuracy of RF phase and can be also introduced to real applications. |
| Key words: phase measurement phase calibration micro frequency changing phase shift |
