Be applied to isolation coupler in microwave debug system

The utility model provides a be applied to isolation coupler in microwave debug system, including base, magnetic conduction apron, phase setting piece, go up the strontium calcium tablet, upward even magnetic sheet, go up ferrite piece, center conductor piece, ferrite piece, even magnetic sheet, strontium calcium tablet, coupler and isolation load down down, be equipped with the magnetic conduction cavity of cylinder on the base, magnetic conduction apron, phase setting piece, go up the strontium calcium tablet, upward even magnetic sheet, go up ferrite piece, center conductor piece, down the ferrite piece, down even magnetic sheet and down strontium calcium tablet top -down stack gradually and fix in the magnetic conduction cavity, be equipped with on the center conductor piece and pass the parietal input of magnetic conduction cavity, load end and output, the load end links to each other with the isolation load, and the output links to each other with the coupler, the coupler is fixed in on the base with the isolation load. This isolation coupler makes up isolator and coupler on same device, has reduced holistic volume, conveniently is applied to the microwave debug system that little volume or modularization expected much.
