METHODS, SYSTEMS, AND NON-TRANSITORY COMPUTER READABLE MEDIA FOR WIDEBAND FREQUENCY AND BANDWIDTH TUNABLE FILTERING

摘要

Methods, systems, and computer readable media for wideband frequency and bandwidth tunable filtering are disclosed. According to one aspect, the subject matter described herein includes a wideband frequency and bandwidth tunable filter that includes: a first signal path for receiving a first input signal from a filter input node and producing a first output signal; a second signal path for receiving a second input signal from the filter input node and producing a second output signal, the second signal path including a filter circuit for adjusting the frequency spectrum of the second output signal; a conditioning circuit for conditioning at least one of the first input signal and the second input signal; a compensation device for adjusting at least one of a phase of the first output signal relative to a phase of the second output signal and an amplitude of the first output signal relative to an amplitude of the second output signal; and a signal combiner for combining the first output signal with the second output signal to produce a filter output signal having a desired frequency spectrum.
