Patent ID: 8639192

Claim:
An RF feedback receiver arrangement for detecting a transmit signal property of a transmit signal of an RF transmit arrangement, the RF feedback receiver arrangement comprising a normal operating phase and a calibration operating phase, comprising: a reference signal provider configured to provide, in the normal operating phase, a first reference signal comprising a first reference signal frequency and provide, in the calibration operating phase, a second reference signal comprising a second reference signal frequency, which differs from the first reference signal frequency; and a signal property detector configured to detect, in the normal operating phase, the transmit signal property based on a combination of the first reference signal with the transmit signal or with a signal derived from the transmit signal; and the signal property detector further configured to acquire, in the calibration operating phase, a calibration signal based on a combination of the second reference signal with the transmit signal or with the signal derived from the transmit signal, wherein the calibration signal describes a disturbing portion introduced into the detected transmit signal property by the RF feedback receiver arrangement itself.
