Abstract

The invention provides a strip line circulator and a TR assembly. The strip line circulator comprises a first shell; the second shell is used for being assembled with the first shell; the cover body is used for being assembled with the second shell; a first cavity is formed between the first shell and the second shell; a second cavity is formed between the second shell and the cover body; the first cavity is internally provided with two ferrite gyromagnetic sleeve sheets and a central conductor located between the two ferrite gyromagnetic sleeve sheets; a uniform magnetic sheet and a permanent magnet are sequentially arranged in the second cavity; the ferrite gyromagnetic sleeve sheet comprises a ferrite wafer and a heat conduction circular ring fixed on the edge of the ferrite wafer in a surrounding manner. The strip line circulator is low in loss, small in heating value, excellent in heat dissipation performance and high in reliability under high-power electromagnetic wave signals, and can well meet the high-power requirement of a TR assembly.

Description

technical field [0001] The invention relates to the technical field of circulators. More specifically, it relates to a stripline circulator and TR assembly. Background technique [0002] The most critical use of the circulator is to realize the directional transmission of microwave signals. The device has three microwave ports. Using the gyromagnetic properties of the ferrite gyromagnetic material, under the action of an external magnetization field, the microwave signal generates Faraday in the gyromagnetic ferrite. The rotation effect causes the microwave signal to rotate at a specific angle, thereby achieving directional transmission. [0003] According to the transmission line structure, the most common ones are microstrip circulator, stripline circulator, and waveguide circulator. Microstrip circulators are small in size and low in power capacity, but are suitable for micro-assembly processes; stripline circulators have average power and are suitable for micro-assembl...
