Microwave pulse power switching system

A microwave pulse power switching system comprising

• a waveguide switching section having a first port and a second port, and having stacked reduced height waveguides which in combination form a full height waveguide having opposite broadwalls, wherein microwave pulse power introduced into the first port of the waveguide switching section is divided between and propagates through the stacked reduced height waveguides of the waveguide switching section,
• each of the stacked reduced height waveguides of said waveguide switching section being loaded with a non-reciprocal ferrite material that is distributed along a substantial portion of the length of the stacked reduced height waveguides, and
• a magnetic field switching circuit for producing a switchable static magnetic field in the ferrite loaded reduced height waveguides of said waveguide switching section, said magnetic field switching including separate generally U-shaped electromagnets, each U-shaped electromagnet being positioned against one of the broadwalls of the full height waveguide, such that the static magnetic field produced thereby passes through the ferrite material contained in the reduced height waveguide, wherein switching of the magnetic field switching circuit switches the static magnetic field in said ferrite loaded reduced height waveguides to thereby cause a change in the phase relationship between the divided microwave pulse power that propagates down the different reduced height rectangular waveguides of said waveguide switching section, and wherein, by actuating said magnetic field switching circuit, the pulse power that emerges from the second port of said waveguide switching section can be changed relative to the pulse power introduced to the first port of the waveguide switching section.

A microwave pulse power switching system comprising

• a rectangular waveguide switching section having a first port and a second port and broadwalls having inner conductive surfaces, and further having a transverse web plate extending longitudinally down said waveguide substantially parallel to the broadwalls of the waveguide switching section to bifurcate said rectangular waveguide switching section into stacked reduced height rectangular waveguides, wherein microwave pulse power introduced into the first port of the waveguide switching section is divided between and propagates through the stacked reduced height rectangular waveguides of the waveguide switching section,
• each of the reduced height rectangular waveguides of said waveguide switching section being loaded with a non-reciprocal ferrite material distributed along a substantial portion of the length thereof, and
• a magnetic field switching circuit, which includes the web plate of said waveguide switching section, for producing a switchable static magnetic field in the ferrite loaded reduced height rectangular waveguides of said waveguide switching section, said magnetic field switching circuit including separate generally U-shaped electromagnets, each U-shaped electromagnet being positioned against one of the broadwalls of the waveguide section, such that the static magnetic field produced thereby passes through the ferrite material contained in the reduced height waveguide, wherein switching of the magnetic field switching circuit switches the static magnetic field in said ferrite loaded reduced height waveguides to thereby cause a change in the phase relationship between the divided microwave pulse power that propagates down the different reduced height waveguides of said waveguide switching section, and wherein, by actuating said magnetic field switching circuit, the pulse power that emerges from the second port of said waveguide switching section can be changed relative to the pulse power introduced to the waveguide switching section.
