There are several methods to couple resonators. For ease of manufacturing and tuning, a common resonator type and coupling method is generally preferable. Matthaei1 proposes what have been termed J admittance and K impedance inverters both to permit a common type of resonator and to serve as coupling elements for the resonators. The J inverters may be represented as the admittance of the element or the value of the characteristic admittance of a quarter-wavelength line in the equivalent circuit that couples the resonators. Similarly, the K inverters may be represented as the impedance of the element or the value of the characteristic impedance of a quarter-wavelength line that couples the resonators. A similar approach to the general design of bandpass filters employing common types of resonators proposes specific coupling elements in the case of lumped resonator bandpass filters or specific proximity methods of coupling in the case of distributed resonator bandpass filters.

This fact will become evident when the coupling between resonators is disclosed to be a function only of the fractional bandwidth and the low pass filter prototype elements.

Fortunately, a measurement technique is available to verify the coupling values of symmetrical resonators, and may also be utilized in multi-resonator filters.

That measurement technique will now be explored. The amplitude response of any pair of symmetrical resonators may be represented by1 In the equation, k is the coupling coefficient between the symmetrical resonators, Qu is the unloaded quality factor of each resonator and Qe is the external quality factor.

The external quality factor is defined to differentiate the source and load coupling and loss from the losses associated with the individual resonators Qu. If the overcoupled condition is satisfied such that it is possible to determine the resonator coupling coefficient from where f0 , fa and fb are subsequently defined. The utility of the equations will be demonstrated by two examples.

Consider the symmetrical, lumped element resonators in the schematic shown in Figure 14 where two, p -type, L-C resonators are coupled by the capacitor Cp , and the external source and load are coupled to the respective resonators by capacitor Ce. Note also the Qu of each resonator is The following variables have been assigned With the assigned variables, the amplitude response is shown in Figure The two peaks in the amplitude response correspond to the frequencies fa and fb.

An equivalent circuit representation of the coupled lines, external coupling and resonator loss is required in order to quantify the coupling factor.

The variables have been assigned as With the assigned variables, the amplitude response is shown in Figure Analog Integrated Circuits and Signal Processing.

This statement understates the importance of resonator coupling to the bandpass filter parameters. Recall that the elements of the low pass prototype filter, from which the bandpass filter is derived, determine completely the characteristics of the resulting filter.
