The invention provides a TM mode dielectric filter and RF communication devices, the TM mode dielectric filter comprises a cavity, and the cavity is arranged on the cover at least two dielectric resonator, covering the cavity, the dielectric resonator through the isolation wall spaced apart to form a resonant cavity of the isolation wall between the cavity adjacent the at least two a coupling slot coupling card groove is provided with a coupling element; the coupling member includes a first coupling part and the second coupling part and connecting part, both ends of the connecting part are respectively connected with the first coupling part and the second coupling part, connecting part through the coupling slot, the first coupling part and the second coupling part of the resonant cavity are respectively arranged on the adjacent first. The coupling and the second coupling part are circular structure, parallel electric field direction plane and dielectric resonator ring structure where, in the first part and the second coupling part coupling The ring structure is provided with a gap, and the notch disconnects the ring structure. The TM mode dielectric filter can produce capacitive coupling and transmit strong electric field energy.
