    Abstract: A system/method describing a physically compact broadband radio frequency (RF) splitter/combiner is disclosed. The system and method provide an alternative to traditional broadband Wilkinson-style RF power splitter/combiners while reducing the overall size of the power divider/combiner to a significantly smaller form factor. The system and method utilize a serpentine impedance network (SIN) that incorporates a mirrored series of positive serpentine node (PSN) traces and negative serpentine node (NSN) traces. The PSN and NSN are coupled together within each isolated and mirrored SIN section with paired coupling traces (PCTs) located between the PSN and NSN traces that serve as both power transformers for the system and as an aid to impedance matching between the RF input port (RIP) and RF output ports (ROPs). The system is electrically symmetric and provides for power splitting and/or combining functionality between the RIP and ROPs.
