Abstract

The invention discloses a miniaturized structural unit for ultra wide band microstrip-coaxial switching. The miniaturized structural unit for ultra wide band microstrip-coaxial switching includes an upper layer S-shaped microstrip line structure, a coaxial feed structure and a lower layer S-shaped microstrip line structure, wherein the upper layer S-shaped microstrip line structure and the lower layer S-shaped microstrip line structure are the same and are arranged in parallel, and the two ends of the coaxial feed structure are connected with the upper layer S-shaped microstrip line structureand the lower layer S-shaped microstrip line structure respectively. The miniaturized structural unit for ultra wide band microstrip-coaxial switching has the advantages of being simple in structure,wide in working frequency band and low in loss and accordingly can be more widely applied to the field of small multilayer integrated circuits.

Description

technical field [0001] The invention relates to the field of microwave passive technology, in particular to a structural unit for miniaturized ultra-broadband microstrip-coaxial conversion. Background technique [0002] Microstrip-to-coaxial conversion structure has become an indispensable microwave passive component in RF test system. As a kind of microwave transmission line, microstrip line mainly has different forms such as parallel line, coaxial line, waveguide, strip line and microstrip line. Coaxial cables and waveguides are large in size, heavy in weight, heavy in machining, and high in cost. The microstrip line structure has the advantages of small size, light weight, high reliability, and good performance, so it has been widely used in the field of microwave passive technology applications. [0003] In the RF test circuit, in order to test the performance of the printed circuit board, the conversion structure of the printed circuit board and the test equipment is ...
