Abstract

The invention discloses a radio frequency interconnection method for a TR assembly and an antenna array plane and aims to provide a radio frequency interconnection method which is high in channel density, good in air tightness and easy to disassemble, assemble and maintain. According to the technical schemes of the invention, an antenna bearing dielectric substrate is tightly pressed on a radio frequency insulator metal substrate through a fuzz button metal substrate; polymer-based composite dielectric tubes vertically corresponding to the lower array surfaces of patch antennas penetrate through the fuzz button metal substrate and are tightly attached to the end surfaces of radio frequency connection insulators; the radio frequency connection insulators integrally sintered on a TR assemblystructural member outer conductor through insulator solder are assembled in the stepped holes of the TR assembly structural member outer conductor in a manner that the radio frequency connection insulators are corresponding to the polymer-based composite dielectric tubes; fuzz button inner cores are tightly pressed on T-shaped probes, and insulator inner conductors are connected with the interconnection end of the TR assembly through glass dielectric insulation bodies filling insulator outer conductor holes and air coaxial matching cavities which are arranged below the glass dielectric insulation bodies and are in sealed matching with the glass, so that a coaxial transmission structure is formed.

Description

technical field [0001] The invention belongs to the field of microwave technology, and in particular relates to a radio frequency interconnection method of a high-density hermetic TR component and an antenna array. Background technique [0002] As phased array antennas enter the millimeter wave frequency band, the integration level of the array level is getting higher and higher, and the spacing between antenna array elements is also shrinking. The element spacing of the phased array antenna above 30GHz will basically be compressed within 5mm. The phased array antenna is equipped with antenna array, feeder, TR components, power supply, cooling system and many other equipment, which is the most complex part of the whole radar. The equipment in the radar phased array antenna is connected with a large number of cables and connectors. Once water seeps into the array, it may cause a short circuit, causing the electrical performance of the antenna to decline or even fail as a who...
