Hollow conductor circulator with three conductor arms and a ferrite body at their junction

摘要

The circulator has three hollow conductor arms, in the branching area of which is a ferrite body (1) through which a magnetic field passes. The ferrite body (1) is fixed on the back of a screw (8) which can be screwed into a threaded bore (7) in a wall of the circulator which is common to all of the arms. The screw is self limiting. At least one threaded bore for a balancing screw is provided in the same wall as the other threaded bore.
