The structure includes a package molded around an RF circuit die with a single redistribution layer (RDL) fabricated on the surface thereof mounted on an RF printed circuit board (PCB) via a plurality of solder balls. Coplanar transmission lines are fabricated on the RDL to conduct RF output signals from the die to PCB signal solder balls. The signal trace transition to the solder balls are funnel shaped to minimize insertion loss and maximize RF isolation between channels. A conductive ground shield is fabricated on the single RDL and operative to shield the plurality of coplanar transmission lines. The ground shield is electrically connected to a ground plane on the PCB via a plurality of ground solder balls arranged to surround the plurality of coplanar RF transmission lines and signal solder balls, and are operative to couple the ground shield to the ground plane on the PCB and provide an electrical return path for the plurality of coplanar transmission lines. Ground vias on the printed circuit board can be either located under the ground solder balls or between them."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Single layer radio frequency integrated circuit package and related low loss grounded coplanar transmission line","description":"A novel and useful a single layer RFIC/MMIC structure including a package and related redistribution layer (RDL) based low loss grounded coplanar transmission line.
