Abstract:
An apparatus for generating an output signal representative of a true transmitted power at a radiating element coupled to an RF feed line, comprising:an RF coupling section, formed on a substrate proximate the RF feed line, for coupling RF power incident at the radiating element and RF power reflected at the radiating element; a first detector, mounted to the substrate and coupled to the RF coupling section, for providing a first voltage representative of the RF power incident at the radiating element; a second detector, mounted to the substrate and coupled to the RF coupling section, for providing a second voltage representative of the RF power reflected at the radiating element; and a differential amplifier, mounted to the substrate and coupled to the first detector and the second detector, for combining the first voltage and the second voltage to provide an output signal indicative of a true transmitted power at the radiating element.
