Coaxial Magnetron Launcher for 2.45 GHz ISM Band

The design procedure and experimental results of a noncontacting coaxial magnetron launcher (CL) are presented, appropriate for a class of 2.45-GHz magnetrons with powers up to about 1.5 kW, with 7/8'' EIA coaxial output. The launcher has been designed for the Panasonic 2M244 magnetron, which is a good representative of this class. The performance of the developed CL has been verified by measuring the Rieke diagram of a 2M244 magnetron installed in a CL prototype.
