8. 4 Microwave Cavity Filters 45 Cavities having rectangular or square cross section could also be used. Distributed capacitance is developed at the free end of the resonator. The inductance of the resonator and the distributed capacitance resonate at a frequency decided by the mechanical dimensions of cavity and resonator. The resonant section is a shunt section. The microwave coaxial cavity with resonator is the basic resonant section in microwave cavity filters. The number of resonant sections in the filters is decided by the electrical specifications of filters.

The expression for determining characteristic impedance, Zo, is [15]: ! 60 1:9H Z0 ¼ pffiffiffiffi ln ohms er 0:8Wð0:8W + tÞ Examples of the application of stripline technology are filters and couplers. Like microstrip circuits, stripline circuits are also enclosed in metal enclosures. 4 Computer Aids for Filter Design Proto-model of filter is needed for verifying compliance to customer specifications. If the filter does not meet the specifications, the application of ‘cut & try’ [2] technique is applied or another proto-model of the filter is fabricated.
