Filed:

Dec 20, 2002

Appl. No.:

10/327254

Inventors:

Christopher L. Trammell - La Habra CA

Assignee:

The Boeing Company - Chicago IL

International Classification:

H01P 512

US Classification:

333137, 333125

Abstract:

A generally Y-shaped ferrite power divider for transferring an RF input from an input port to either one of two outlet ports or to both outlet ports in an equal or unequal fashion. The input port and the two output ports meet at a junction. An internal magnetic return is positioned in the junction and is in communication with an upper magnetic return and a lower magnetic return. An upper ferrite puck is positioned at the junction above the internal magnetic return and a lower ferrite puck is positioned at the junction below the internal magnetic return.

Abstract:

A resonant waveguide load structure is provided for use in waveguide systems. The load structure includes a length of waveguide which is open at one end and closed at the other end. The load structure also includes a support pin mounted inside the waveguide near the closed end thereof. The load structure further includes a resonant body mounted on the support pin. The load structure also includes at least one spacer member mounted on the support pin for maintaining the position of the resonant body. This load structure may be combined with a waveguide circulator to provide a novel waveguide equalizer apparatus.
