According to each case, the equivalent circuit of coupling is expressed by inductive or capacitive coupling, respectively, see Figure 1. M C 1(b)

43、resonance circuit elements; M is the mutual inductance; C mis the coupling capacitance; k is the coupling factor. Page6 EN613371:2004In the case of a symmetrical circuit of coupling, the coupling factor can be obtained from two resonance frequencies calculated or measured for the coupled resonators:

The coupling factor of a band-stop filter is the degree of co
45、upling between the resonator and the transmission line. The coupling factor k is defined as the ratio of the external power loss (P e ) of the resonator system to the internal power loss (P u ) of the resonator and can be expressed by a function of quality factor as follows: 1 = = = L u e u u e Q Q
