Title (EN) QUADRATURE SIGNAL GENERATOR, BEAMFORMING ARRANGEMENT, COMMUNICATION DEVICE AND BASE STATION
(FR) GÉNÉRATEUR DE SIGNAUX EN QUADRATURE, AGENCEMENT DE FORMATION DE FAISCEAU, DISPOSITIF DE COMMUNICATION ET STATION DE BASE
Abstract: front page image
(EN)A quadrature signal generator comprises a resistor-capacitor, RC, polyphase filter and an inductor compensation arrangement. The inductor compensation arrangement comprises a first inductor connected between the first and the third output terminals, and a second inductor connected between the second and fourth output terminals. The first and second inductors are arranged to compensate for a capacitive load on the output terminals when in use. A beam forming arrangement, a communication device and a base station are also disclosed.
(FR)L'invention concerne un générateur de signaux en quadrature qui comprend une résistance-condensateur RC, un filtre polyphase et un agencement de compensation d'inductance. L'agencement de compensation d'inductance comprend une première bobine d'induction raccordée entre la première et la troisième borne de sortie et une seconde bobine d'induction raccordée entre la deuxième et la quatrième borne de sortie. Les première et seconde bobines d'induction sont agencées de sorte à compenser une charge capacitive sur les bornes de sortie lors de l'utilisation. L'invention concerne également un agencement de formation de faisceau, un dispositif de communication et une station de base.
