Abstract
A manifold is constructed with a primary manifold section to which the input wave guides are connected and a tuning section attached to the output of the primary manifold section. The tuning section is constructed of a deformable material which allows the dimpling of the internal wall to alter the impedance of the waveguide system for the purpose of fine tuning the impedance matching of the manifold.
Claims10
In a multiplexer for conducting multiple channels of a microwave communications signal having an input section comprising at least one waveguide and filter assembly for receiving and conducting microwave energy, a manifold comprising:
- an internal chamber connected to the input section for receiving microwave energy from said input section, said manifold constructed with a tuning section coupled to said manifold to form a continuous interior chamber therewith, said tuning section constructed of a deformable material and comprising an exterior wall to permanent deformations are made to alter the impedance of the manifold.
A method for tuning a manifold of a multiplex waveguide system constructed to conduct multiple channels of a microwave communications signal within an internal chamber comprising the steps of:
- constructing a tuning section of deformable material having an exterior wall enclosing an interior chamber;
- coupling said tuning section to the manifold to form a continuous internal chamber therewith;
- deforming said exterior wall of said tuning section to alter the impedance of the manifold.
