ABSTRACT:
A millimetric wave high-pass filter is assembled from two axially-separate halves. Each half comprises a cast metal body having a channel which is divided to form two wave guides by means of a metal strip. The dimensions of the wave guides of the filter as a whole decrease towards a constriction at their centers while the strip is relatively thick at the constriction and tapers towards the ends. This configuration makes it possible to cast the filter in two halves with the body and the strip of each half being cast in a single piece. When assembled the halves meet at the level of the constriction.
