Abstract: Power dividers (or splitters) and power combiners may be implemented using distributed lossy transmission lines that dissipate radio frequency (RF) and other electromagnetic (EM) signal energy. By taking advantage of natural PCB board loss at high operating frequencies, N-way power dividers with matched outputs and good isolation may be implemented without the use of discrete resistors. In one embodiment, a N-way power divider may be at least partially implemented on buried printed circuit board (PCB) layers (e.g., partially embedded) and, in a further embodiment a N-way may be implemented in a manner that is completely internal to the PCB (e.g., completely embedded), without the use of discrete resistors.
