Novel high-integration W/V wave band front end and manufacturing method thereof

The invention provides a novel high-integration W/V wave band front end. The novel high-integration W/V wave band front end comprises an integrated feed network based on multiple layers of media, an array antenna and a TR assembly with airtight characteristics. An antenna unit of the array antenna comprises two blind cavities which are formed in a multi-layer dielectric substrate and are isolated by a metal layer, and metal holes are formed in the peripheries of the blind cavities; the feed network is connected with the antenna unit and the TR assembly. The TR assembly comprises an assembly structure, a plurality of system-level packaging modules and a waveguide power division network; a metal enclosure frame is arranged around a dielectric substrate of each system-level packaging module, and the dielectric substrate comprises a first area and a second area which are subjected to signal isolation through an isolation ridge; the first area is provided with a first external radio frequency port and a bidirectio
