JPS5580902A - Waveguide-type ferrimagnetic substance phase shifter - Google Patents

Abstract

PURPOSE:To set free the heat generated in the ferrimagnetic substance to the waveguide and furthermore to outside through the heat pump by distributing the heat exchanger possessing the tubular flow path in such way that a contact may be secured between the ferrimagnetic substance and the upper or lower wall of the waveguide. CONSTITUTION:Ferrimagnetic substance 2 is distributed so that a contact may be secured between upper and lower wall of waveguide 1 and substance 2. Then hole 3 is provided to substance 2, and then lead wire 4 is made to pass through the center of hole 3. Thus a phase shifter is formed. Here the heat generated at substance 2 must be discharged outside in order to improve the average power properties of the phase shifter. The heat exchanger possessing the tubular flow path is applied to secure the heat discharge of a high efficiency in such way that heat pipe 7 the container of which is made of the conducting metal cooling the condensation part outside the waveguide is distributed to secure a contact to substance 2. As a result, the heat generated in substance 2 can be discharged outside waveguide 1 through heat pipe 7 as well as toward waveguide 1.
