An injector device for microwave filter units made up of channel filters (1″, 1″′) 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 (15″, 15″′) 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 (16) 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 (13) of the resonator via electrical coupling means. The invention also relates to filter units equipped with such injector devices.
A channel filter injector device for a microwave filter unit using dielectric resonators and including a plurality of channel filters with communicating dual mode cavities, each channel filter including a filter input cavity receiving a signal to be processed transmitted by a coaxial cable via a connector mounted through a wall closing said input cavity at an entry end of the filter, characterized in that the signal acts electrically on a resonator dielectric element housed in said input cavity via a probe consisting of a L-shaped rod having a first portion connected to the core of the coaxial cable, the first portion extending into said input cavity, and a second portion which acts on said resonator dielectric element via electrical coupling means.
A microwave filter unit including a plurality of channel filters with communicating dual mode cavities that contain dielectric filters, each channel filter including a filter input cavity receiving a signal to be processed transmitted by a coaxial cable via an input connector mounted through a wall closing said filter input cavity at an input end of the filter, wherein the microwave filter comprises an injector device associated with said filter input cavity of each channel filter and acting through electrical coupling means on a resonator dielectric member housed in said filter 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 said filter input cavity and a second portion that acts on said resonator dielectric element via coupling means.
