Problems solved by technology

[0005] It can be seen from the above description that the existing high-frequency insulator has a relatively simple structure. In the ultra-broadband vertical interconnection system, an additional matching circuit needs to be assembled. The size of the additional matching circuit is generally large, and its assembly error when welding with the insulator It will deteriorate the transmission performance; and it is prone to reliability problems such as virtual welding and short circuit during the welding process
It is difficult to adapt to the development needs of high-density ultra-wideband transmission and microsystem integration of electronic equipment

Abstract

The invention discloses a self-matching ultra-broadband microwave insulator, comprising: a housing, a glass column, an inner conductor and a matching pad; the glass column is arranged in the outer casing, and the inner conductor is arranged in the glass column; the The inner conductor has an upper bump and a lower bump protruding from the glass column; the matching pad includes an upper pad and a lower pad of a gold-plated layer, which are used for bonding with a circuit chip through a gold wire or a gold ribbon, and the upper solder The pad and the lower pad are respectively welded to the upper bump and the lower bump, and the dimensions of the upper pad and the lower pad are determined through simulation design according to the requirements of ultra-wideband microwave transmission. The present invention improves the ultra-wideband transmission performance of microwave signals by adding matching pads at the end of the inner conductor; the matching pads are plated with gold to be suitable for bonding of gold wires or gold ribbons, and avoid insulators and circuit chips Welding, thereby greatly reducing the size of the vertical interconnection structure, improving interconnection density and assembly reliability.

Description

technical field [0001] The invention relates to the technical field of ultra-wideband microwave interconnection, in particular to a self-matching ultra-wideband microwave insulator. Background technique [0002] With the urgent demand for arraying and miniaturization of military electronic equipment, microwave insulators for interconnection and transmission of microwave signals are also developing in the direction of wider frequency band, higher frequency, smaller size and higher density. Most of the patents related to insulators are concentrated in the field of electrical engineering, and there are few patents on broadband microwave insulators. [0003] Chinese patent CN105304977A discloses a millimeter-wave ceramic insulator and its design method, which is mainly processed into a stripline and microstrip transition structure by high-temperature co-fired ceramic technology, and mainly solves the functions of signal horizontal transmission and device packaging. [0004] Chi...
