A Bandpass Filter Using Electrically Coupled TMo16 Dielctric

A compact bandpass filter having Chebyshev, low-loss and good spurious response is constructed by placing high-Q TM dielectric rod resonators coaxially in a TMOlol'cutoff circular waveguide. A precise design o f interresonator coupling is performed by the mode matching technique. The interresonator coupling is equivalently expressed by a capacitively coupled LC resonant circuit. the high-Q resonators and
