Abstract

A new compact NRD-guide mode suppressor is proposed in this paper for wideband applications in NRD integrated circuits. Rigorous field-theoretical analysis and optimum design are carried out to determine frequency response of the proposed mode suppressor using a filter-like scheme. It is found that the transmission loss of a three-section mode suppressor is better than -30 dB over the frequency band of interest. In addition, the length of the whole resulting mode suppressor becomes shorter than its counterpart using the choke metallic pattern by 20%.<>
