Original Abstract Submitted
circuits and methods that provide fine-resolution measurements of rf signal power within a communication system band, thereby more accurately measuring rf interference or the potential of rf interference. one aspect of embodiments of the present invention is a narrow-band tunable filter that includes two elements coupled in series, a periodic passband filter and a tunable filter. the purpose of the periodic passband filter is to generate multiple periodic passbands for an applied rf signal. the purpose of the tunable filter is to generate a single passband, generally with a tunable center frequency. by serially coupling the two filter types in either order, the single passband of the tunable filter is superimposed over one of the periodic passbands of the periodic passband filter, synergistically resulting in an extremely narrow passband.
