INTEGRATED CIRCULATOR FOR PHASED ARRAYS

摘要

A circulator/isolator assembly to operate within a first frequency range is disclosed. The assembly includes a first magnetic substrate having a first surface and a second surface and a first ground plane formed on the first surface, a dielectric layer disposed adjacent the first magnetic substrate, the dielectric layer comprising a multi-port junction circuit disposed on a first side of the dielectric layer and dimensioned to be resonant within the first frequency range, the multi-port junction circuit comprising a conductive disk coupled to a plurality of RF transmission traces, a first RF transmission trace forming an input port and a second RF transmission trace forming an output port, a ground plane disposed on a second side of the dielectric layer, and a first magnetic cylinder disposed proximate the multi-port junction circuit of the dielectric layer.

1. A circulator/isolator assembly to operate within a first frequency range, comprising:
a first magnetic substrate having a first surface and a second surface and a first ground plane formed on the first surface; a dielectric layer disposed adjacent the first magnetic substrate, the dielectric layer comprising a multi-port junction circuit disposed on a first side of the dielectric layer and dimensioned to be resonant within the first frequency range, the multi-port junction circuit comprising:
a conductive disk coupled to a plurality of RF transmission traces, a first RF transmission trace forming an input port and a second RF transmission trace forming an output port;a ground plane disposed on a second side of the dielectric layer; anda first magnetic cylinder disposed proximate the multi-port junction circuit of the dielectric layer, such that the first magnetic cylinder excites a circular, unidirectional magnetic flux field in the first magnetic substrate that limits electromagnetic wave propagation to a single direction of the multi-port circuit junction circuit.
