Systems and methods according to one or more embodiments are provided for a distributed gain function. The distributed gain function may be implemented, for example, as a second amplification stage to maintain amplification in an RF distribution network (218a, 218b, 220) of a compact high gain phased array antenna system. In one example, a system comprises a plurality of element circuits (213), each coupled to one or more antenna elements (536). Each element circuit (213) comprises a first amplification stage. A distribution network (218a, 218b, 220) configured to couple the plurality of element circuits (213). A distributed gain circuit (217) coupled to the plurality of element circuits (213) and the distribution network (218a, 218b, 220), wherein the distributed gain circuit (217) comprises a second amplification stage. The antenna elements (536) and the distribution network (218a, 218b, 220) are integrated in a substantially planar circuit board (539) and the plurality of element circuits (213) are coupled to the circuit board (539). Additional systems and methods are also provided. |
