Abstract

The invention relates to a high-reliability K-type radiofrequency coaxial terminal load. The high-reliability K-type radiofrequency coaxial terminal load is a precision microwave passive device capable of realizing terminal impedance matching of microwave signal transmission paths and completely absorbing transmission energy of coaxial lines. The high-reliability K-type radiofrequency coaxial terminal load comprises a connecting nut, a washer, a snap spring, an insulating support assembly, a shell, four metal foil resistors, soldering tin, a gland and the like which are assembled. Microwave signals with frequencies ranging from low frequencies to 40GHz high frequencies can be received, most of the signals are absorbed, accordingly impendence matching of the signals is guaranteed, and signal leakage at idle ports and mutual interference among systems are greatly reduced. Compared with the traditional K-type load, the high-reliability K-type radiofrequency coaxial terminal load has the advantages that the high-reliability K-type radiofrequency coaxial terminal load is novel in structure, high in reliability, broad in frequency band, excellent in performance and wide in application prospect and is ultra-small, the quantity of standing waves is low, and the like.

Description

technical field [0001] The invention relates to a highly reliable K-type radio frequency coaxial terminal load, which belongs to the technical field of microwave high-precision passive devices. Background technique [0002] The RF coaxial terminal load is a precision microwave passive device that realizes the terminal impedance matching of the microwave signal transmission path and the complete absorption of the energy transmitted by the coaxial line. It is widely used as the matching load of radio equipment for high-frequency signal output and the spare channel of radar TR components. It is also widely used in aerospace payload equipment and microwave test engineering. It is one of the key components of the satellite signal transceiver system. [0003] With the rapid development of the communication satellite business and the extensive demand for aerospace applications, its working frequency band continues to expand to high frequency bands, and its reliability requirements ...
