RF RECEIVER MISMATCH CALIBRATION SYSTEM AND METHOD |
摘要 |
A calibration system for an RF system that includes an RF receiver capable of operating in a normal mode and in a calibration mode. The calibration system includes a phase delay unit provided on at least one of an I channel output and a Q channel output of the RF receiver. The system further includes a phase detector configured to detect a phase difference between the I channel output of the RF receiver and the Q channel output of the RF receiver. The system also includes a calibration control unit configured to provide a digital calibration control signal to the RF receiver based on the phase difference as provided by the phase detector. |
