Abstract The disclosed embodiments include multi-channel communications filters, multi-channel communications systems, apparatuses that utilize a tunable multi-channel communications filter for antenna tuning, and methods to perform multi-channel communications filter tuning. A multi-channel communications filter includes a coupled inductor having a primary winding that is coupled to a power source, and magnetically coupled to one or more secondary windings. The multi-channel communications filter also includes a tuning bank formed from a first set of capacitors; and a first set of switches that are configured to adjust capacitance of the first set of capacitors to impede signals having a first frequency range from flowing through the multi-channel communications filter. The tuning bank and the first set of switches are coupled to the one or more secondary windings. Les modes de réalisation de l'invention comprennent des filtres de communications multicanaux, des systèmes de communication multicanaux, des appareils qui utilisent un filtre de communication multicanal accordable pour l'accord d'antenne, et des procédés pour effectuer l'accord du filtre de communication multicanal. Un filtre de communication multicanal comprend une inductance couplée dont l'enroulement primaire est couplé à une source d'alimentation, et couplé magnétiquement à un ou plusieurs enroulements secondaires. Le filtre de communication multicanal comprend également un banc d'accords formé d'un premier ensemble de condensateurs ; et un premier ensemble de commutateurs qui sont configurés pour ajuster la capacité du premier ensemble de condensateurs afin d'empêcher les signaux appartenant à une première plage de fréquences de traverser le filtre de communication multicanal. Le banc d'accord et le premier ensemble de commutateurs sont couplés à un ou plusieurs enroulements secondaires.
