Abstract
An injector device for microwave filter units made up of channel filters ( ) provided with cavities housing dielectric resonators. Each filter has an input cavity which receives a signal transmitted by a coaxial cable terminating at a connector ( ) mounted through a wall closing the cavity at an input end of the filter. The injector device of a filter acts electrically on a dielectric resonator accommodated in the input cavity via a probe ( ) consisting of a L-shaped rod having a first portion connected to the core of the coaxial cable to extend it into the cavity and a second portion acting on a dielectric element ( ) of the resonator via electrical coupling means. The invention also relates to filter units equipped with such injector devices.
