Abstract

Power detector integrally formed within a printed transmission line to capacitively couple a portion of signal power propagating on the printed transmission line and a power detector circuit that receives coupled power output from the power detector to detect a power level of the signal power. The power detector is designed such that capacitance of the coupling capacitor is absorbed into a distributed capacitance of the transmission line to maintain continuity of a characteristic impedance of the transmission line.
