Patent

CA 2197887

An N-way power divider/combiner (30) having isolated outputs (32) using printed circuit board geometry that forms a ring of power resistors (37) and output transmission lines (34) 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.

Diviseur/combineur de puissance (30) à N voies présentant des sorties isolées (32) utilisant une géométrie de plaquettes de circuit imprimé formant un anneau de résistances de puissance (37) et des lignes de transmission de sortie (34) disposées en spirale autour de l'anneau pour réduire la taille du circuit. Les deux côtés de la plaquette de circuit imprimé servent à obtenir d'autres avantages en matière de taille. L'invention fournit donc un diviseur/combineur de fréquences radio puissant, de taille nettement plus réduite les circuits antérieurs pouvant gérer des niveaux de puissance équivalents.
