Distributed 3 Port Isolator Assembly
Model 102647NP
(Patent No. 6,407,646,B1)
 

This Isolator Assembly consists of the EM Design Distributed Three Port Circulator without sampling probes and an EM Design Waterload - Model R284-3.0.

The input Port 1 is attached 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 S band circulator is based on EM Design's unique patented concept and is especially attractive for isolating reflection from resonant loads such as accelerators and other similar devices. This isolator assembly is set for the 2.998 GHz but can be readily optimized for other frequencies, including 2.856 GHz. Water cooling is connected in series so that the flow is conveyed through the ciruclator and the attached load.
