Microstrip Filters Provide High Harmonic Suppression
Two different bandpass filter structures were evaluated for achieving good harmonic suppression at microwave frequencies.Harmonic filters are invaluable for removing unwanted higher-order harmonic signals from microwave multipliers and mixers in receiver designs, among other applications. Although a variety of filter configurations have been developed to reduce the level of harmonic...
