Ceramic filter with CTE compensation

The invention discloses a ceramic filter with CTE compensation. The ceramic filter comprises a filter body. The signal transmission surface of the filter body is provided with an input end and an output end. The ceramic filter is free of a connecting PCB, can effectively reduce use cost, can improve the buffer performance during connection with a communication system board and can reserve the functions of supporting the filter, connecting signals to the ground and compensating CTE inconsistency of the ceramic and the communication system board when the PCB is used; the ceramic filter with CTEcompensation further comprises a plurality of first elastic metal bonding pads used for being connected with the communication system board; the first elastic metal bonding pads are discretely arranged on the signal transmission surface and are staggered with the input end and the output end; and the thermal expansion coefficient of the first elastic metal bonding pad is equivalent to the thermalexpansion coefficient of t
