Abstract
In a Radio Frequency (RF) filter, a first conductive link has a first length corresponding to a first (N) number of wavelengths of a primary RF frequency. A second conductive link has a second length corresponding to both a second (M) number of wavelengths of the primary RF frequency and an out-out-phase (X) number of wavelengths of a secondary RF frequency. An input interface receives an input RF signal and transfers a first component of the input signal over the first link and transfers a second component of the input RF signal over the second link. An output interface combines the first component from the first link with the second component from the second link to transfer an output RF signal. The energy at the primary frequency constructively combines in-phase, but the energy at the secondary frequency destructively combines out-of-phase.
