Active quadrature radio frequency power detector

摘要: The present invention is a quadrature RF power detector circuit, which used in conjunction with amplifier to detect and combine signals from an in-phase leg quadrature-phase provide detection signal. circuit includes emitter follower for each of the may include doubler circuitry both half-cycles provides minimal DC current without significant loading at point detection, such as interstage. This balanced also more accurate under high VSWR conditions due action minimizing peaks valleys detected voltage.
