Abstract
An N-way power divider/combiner having isolated outputs using printed circuit board geometry that forms a ring of power resistors and output tramsmission lines spiraling around the ring to reduce the size of the circuit is disclosed. Both sides of the printed circuit board are used to achieve further size advantages. The invention thus provides a high-power radio frequency divider/combiner circuit that is much smaller than previous circuits that are able to handle equivalent power levels.
