Abstract
A method and apparatus is disclosed herein for measuring radio-frequency energy. In one embodiment, the apparatus comprises one or more antennas, a wideband radio frequency detector (e.g., a logarithmic amplifier (LogAmp)) coupled to the one or more antennas to measure ambient RF energy, wherein the wideband radio frequency detector has an analog output indicative of RF input power received by the one or more antennas, and an analog-to-digital converter coupled to the wideband radio frequency detector to convert the analog output to a digital value, the digital value being applied to a calibration function, to provide a number representing RF energy.
