Abstract
Provided is a Radio Frequency (RF) communication apparatus and a method for detecting power. The RF communication apparatus includes a receiver that receives a segment value indicating one of multiple transmission output power ranges, a power detector that detects a strength of an RF transmission signal in an output power range corresponding to the segment value, and a transmitter that transmits the strength of the detected RF transmission signal. The power detector includes a feedback unit that receives the fed-back RF transmission signal, an RF core unit that generates a Root Mean Square (RMS) of the RF transmission signal, and a converter that converts a current signal corresponding to the RMS of the RF transmission signal into a voltage signal, and converts the converted voltage signal from a differential signal to a single signal.
