Abstract

The invention discloses a three-centimeter frequency fast switch capable of withstanding 70kW peak power and 100W average power. A star-shaped ferrite is arranged inside a T-shaped waveguide junction, and an insulating layer is arranged outside the star-shaped ferrite. It adds an insulating layer around the ferrite, and improves the formula and process of the ferrite material, so that it can withstand 70kW peak power and 100W average power.

Description

technical field [0001] The invention relates to the field of a three-centimeter frequency band fast switch, in particular to a three-centimeter frequency band fast switch capable of withstanding 70KW peak power and 100W average power. Background technique [0002] The existing three-centimeter frequency band fast switch is developed for the radar receiving branch, and its purpose is to replace the discharge tube switch and access the receiving branch. The product structure is as figure 1 As shown, the T-shaped waveguide junction 1' is provided with a star-shaped ferrite 2'. A star ferrite structure such as figure 2 shown. The excitation line passes through the interior of the ferrite, a large pulse current flows through the excitation line, and a strong magnetic field is generated instantaneously, so that the T-junction switch forms an instantaneous circulator. The direction of the instantaneous circulator changes with the direction of the pulse current. If A fully matc...
