Beschreibung
Zusammenfassung:	A transceiver includes a transmitter (240), a frequency synthesizer (230) coupled to the transmitter (240), a receiver (220) coupled to the frequency synthesizer and a voltage sensor (270); and a digital controller (262) coupled to the voltage sensor, the receiver, and the transmitter, wherein based on a DC voltage measurement of an IF signal made by the voltage sensor (270), a relative phase adjustment occurs of a relative phase associated with a local oscillator, LO, port and a radio frequency, RF, port of the receiver.
