The object of research in this work were chosen two 4-shift filter on 2 resonator ceramic monoblocks, made by hot casting technology of ALTC ceramics. 

The main purpose of the work was determination of influence of additional grinding time on electrical parameters of BPF. The main criteria were chosen: further improvement of the squared-off ratio of BPF. 

Further work on the effect of density increase on electrical parameters of band-pass filter at the process stage of mass grinding is described. 

Results of sharper transition from bandwidth to suppression band and decrease of BPF rectangle coefficient are obtained. A version of further improvement of the technology of making ceramic housings for two-resonator monoblocks is proposed.
