Abstract :
Practical multiple-mode degeneracies of rectangular cavities which are directly applicable to multimode bandpass filter designs are presented. A six-pole, Ku-band, pseudoelliptic, single-cavity bandpass filter has been successfully designed and built. Since all interresonator couplings were realized via tuning screws, fabrication and alignment were greatly simplified. This design offers significant savings in mass and volume compared to dual- and triple-mode, six-pole filter designs with equivalent Qs.<>
