Phased array antenna system utilizing a beam forming network

A phased array antenna system comprising:

• a printed wiring board formed in rhombic shape that accommodates requirements for low observability;
• a beam forming network located within the printed wiring board, wherein the beam forming network is located over substantially the entire printed wiring board, wherein the beam forming network includes at least one subarray of a plurality of beam forming elements, wherein data and clock lines of the beam forming elements are arranged in an orthogonal style to provide an efficient layout of the printed wiring board and robust signal integrity for the array beam steering control;
• wherein the subarray comprises a plurality of subarray elements, a module shim coupled to the plurality of subarray elements, a multilayer wiring board coupled to the module shim, a connector shim coupled to the multilayer wiring board;
• and a pressure plate coupled to the connector shim, wherein two or more subarrays are coupled together to provide a rhombic shaped array;
• and
• connectors located on the backside of the printed wiring board that allows for expansion of the system.
