摘要

A coaxial resonator filter (30) comprises a wall construction (50) and a plurality of resonators (11-18) mounted in the shell construction (50) for forming a multi-circuit filter. The filter (30) comprises a connecting portion (19) which combines the resonators (11-18), and said connecting portion (19) and the resonators (11-18) are made in one piece, and the resonators extend as long pin-like projections away from the connecting portion, and said resonators made in one piece are located in different sections (41-48) of the shell construction (31) of the coaxial resonator filter.
