摘要： A balanced-type strip-shaped dielectric substrate integrated filter includes: a high-k dielectric substrate; and first low-k dielectric substrates, second low-k dielectric substrates and metal grounds are symmetrically stacked on upper and lower surfaces of the high-k dielectric substrate. Compared with an existing balanced-type dielectric filter, a high Q-value strip-shaped dielectric substrate integrated resonator with a packageable characteristic which works in TM111 mode and employs strip-shaped dielectric blocks with double grooves, combined with air groove structures of upper and lower layers and a packaging substrate is proposed, so that problems that cost is high and self-packaging cannot be realized of the existing balanced-type dielectric filter when being implemented by combining ceramic dielectric with a metal chamber structure can be solved, and thereby a balanced-type strip-shaped dielectric substrate integrated filter with the characteristic of low loss is realized; and meanwhile the filter may have advantages of self-packaging, high integration level and low cost.

摘要： Embodiments relate to the field of technologies of components of communications devices, and provide a dielectric filter, which resolves a problem that a solid dielectric filter has a difficulty in implementing capacitive coupling. The dielectric filter includes at least two dielectric resonators, where each of the dielectric resonators includes a body made of a solid dielectric material, and an adjusting hole located on a surface of the body. The adjusting hole is a blind hole, configured to adjust a resonance frequency of the dielectric resonator on which the blind hole is located. The bodies of all the dielectric resonators included by the dielectric filter form a body of the dielectric filter.

摘要： A resonator for a filter includes a resonator housing, in which a resonator space is formed. The resonator further includes a dielectric arrangement arranged in the resonator space including a first dielectric element and a second dielectric element, the first dielectric element and the second dielectric element being separated from one another in such a way that a gap is formed between them. Both a first thermal expansion coefficient of the first dielectric element and a second thermal expansion coefficient of the second dielectric element are less than a thermal expansion coefficient of the resonator housing. A temperature-related variation of the resonant frequency of the resonator can therefore be compensated for.
