METHOD FOR TUNING OF MULTILINK BAND FILTERS Russian patent published in 2009 - IPC H03H7/12 H01P1/20 

FIELD: radio engineering.

SUBSTANCE: invention is intended for fine tuning of multilink band filters (hereinafter referred to as filters) of radio electronic devices of microwave and in compliance with the specified requirements. Result is achieved by tuning of filter by specific points of frequency dependence of transfer coefficient (maximum point (7) - in regulation of links, point of maximum slope (6) - in tuning of resonators) at partial connections of filter into measuring track of device, which make it possible to simultaneously control both frequency of resonator tuning and links size. At the same time calculation is simplified for variation of resonator tuning frequency and links size. Method makes it possible to tune two and more filters with the same parametres. It is not required to make any absorbers, accessories for shorting, devices for energy drain.

EFFECT: lower labour intensiveness of tuning process.
