5Description

The board is the bridge between an FPGA and the mechanical and RF front end of an antenna system. Ten layers were needed to keep the high-speed digital buses clean while routing power and control across more than six hundred placed components.

Layout work focused on controlled impedance for the FPGA interfaces, careful plane splitting between the digital and analogue domains, and a stack-up that stays manufacturable at volume.
