Abstract
Filter devices are provided herein. A filter device includes a plurality of low-band resonators and a plurality of high-band resonators. In some embodiments, adjacent ones of the plurality of high-band resonators are spaced farther apart from each other than adjacent ones of the plurality of low-band resonators are spaced apart from each other.

A filter device comprising:
- a plurality of low-band resonators;
- and
- a plurality of high-band resonators comprising only negative couplings with each other.
A filter device comprising:
- a plurality of low-band resonators;
- and
- a plurality of high-band resonators,
- wherein adjacent resonator heads of the plurality of high-band resonators are spaced farther apart from each other than adjacent resonator heads of the plurality of low-band resonators are spaced apart from each other, and
- wherein adjacent stalks of the plurality of high-band resonators are spaced farther apart from each other than adjacent stalks of the plurality of low-band resonators are spaced apart from each other.
2 more elements
A filter device comprising:
- a low-band filter;
- a high-band filter;
- and
- a first ohmic connection that is between the low-band filter and the high-band filter and that electrically couples the low-band filter and the high-band filter to a common port of the filter device.
