One with the inclusion of additional resonators linked disadvantage is that the length of the filter is increased, which is not desirable or possible in some applications, for example, due to space limitations on the motherboard of a customer.

0005The attenuation characteristic of a filter can be increased by both a direct and by a cross-coupling of the resonators as well, such as in the <patcit><text>US Pat. No. 7,714,680</text></patcit> at Vangala et al. is disclosed, which discloses a monoblock filter with both an inductive direct coupling and a quadruplet cross-coupling of resonators that are partially generated by respective metallization that are defined on top of the filter and extend between selected ones of the Resonatordurchgangslöcher to the provide revealed direct and cross-coupling of the resonators.

0006The direct and cross-coupling of the type described in the <patcit><text>US Pat. No. 7,714,680</text></patcit> at Vangala et al. is disclosed and includes the Oberseitenmetallisierungsmuster, is in waveguide filters of the type in the<patcit><text>US Pat.
