Abstract

A broadband multiple input, multiple output switch matrix. The switch matrix comprises multiple crosspoint switch element tiles. Each tile comprises RF MEMS switches disposed on a substrate to provide a crosspoint switching capability. The crosspoint switch element tiles are disposed in a flip-chip manner on the upper side of an RF substrate that provides RF connectivity between the various crosspoint switch element tiles. A bias line substrate disposed on the lower side of the RF substrate receives control signals for the crosspoint switch element tiles and routes the signals through the RF substrate using vias in the RF substrate.
