A new coaxial multi-coupler that is relatively inexpensive and efficient to manufacture in a low volume and high product mix manufacturing environment. A plurality of coaxial resonators are bonded together to form the multi-coupler. Then, at least one coupling hole is formed for capacitively and/or inductively coupling at least two of the resonators together. Formation of coupling holes upon bonding the resonators together allows for improved manufacturing techniques, convenient fine-tuning of coupling between resonators, and significantly better overall filter/multi-coupler performance as compared with the prior art. One reason for this is that precise alignment of the resonators during bonding is unnecessary according to aspects of the present invention.
