Dual mode dielectric resonator loaded cavity filter

A method, comprising operating a dual mode dielectric resonator (DR) filter, the DR filter comprising a first DR, at a HE12δ mode within a first frequency band while exhibiting a quality factor (Q) of no less than 5000.

A dual mode dielectric resonator (DR) filter comprising a first DR, wherein:

• the filter is configured to operate at a higher order mode within a first frequency band while exhibiting a quality factor (Q) of no less than 5000;
• and
• a first characteristic size of the first DR is substantially similar to a size of a second DR, said second DR being configured to operate in a conventional DR filter at a lower order mode within a second frequency band, the second frequency band being substantially lower than the first frequency band.
