Overview

This Isolator Assembly combines an EM Design Distributed 3-Port Circulator, without sampling probes, and an EM Design Waterload, Model R187.

The straight input Port 1 is on the left side and the output Port 2 is shown on the right side of the photograph.  The power reflected at Port 2 is absorbed by the load on Port 3.

The high power C-Band circulator is based on EM Design’s unique patented concept and is especially attractive for isolating reflection from resonant loads such as accelerators or other similar devices.  This isolator assembly is set for the 5.712 GHz frequency.  Water cooling is connected in series so that the flow is conveyed through the circulator and the attached load.

Patent No. 6,407,646
