Abstract :
The realization of optimum-response, narrow bandpass filters in high-Q TE/sub 0ml/ cylindrical resonator modes is described. Experimental results are presented for 15- and 28-MHz bandwidth, 4-pole, elliptic function filters centered at 17.52 GHz using the TE/sub 021/ mode. Unloaded Q´s of 25,000 have been achieved with cavity shaping to suppress TM/sub 1ml/ mode degeneracy.
