Abstract

Filtro paso-banda multi-banda de microondas con un número arbitrario de bandas de paso. Esta estructura está formada por la conexión en cascada de varios bloques. Las secciones de interferencia transversal de señales, basadas en dos líneas de transmisión en paralelo (2 y 4), confieren la acción filtrante multi-banda al circuito total. Las etapas de entrada y salida (1 y 5) son líneas de transmisión adaptadoras que minimizan las pérdidas de retomo de potencia en las bandas de paso. El elemento intermedio (3) es una línea de transmisión que permite la conexión adecuada de las secciones interferenciales para aumentar el rechazo de potencia fuera de banda. Se trata de una topología filtrante compacta y de alta selectividad, apta como circuito selector de bandas en aplicaciones de comunicaciones multi-canal y sistemas radar multi-frecuencia.Multi-band microwave band-pass filter with an arbitrary number of step bands. This structure is formed by cascading several blocks. The cross-sectional signal interference sections, based on two parallel transmission lines (2 and 4), give the multi-band filter action to the total circuit. The input and output stages (1 and 5) are adaptive transmission lines that minimize losses of power return in the passbands. The intermediate element (3) is a transmission line that allows the proper connection of the interference sections to increase the rejection of out-of-band power. It is a compact and high selectivity filter topology, suitable as a band selector circuit in multi-channel communications applications and multi-frequency radar systems.
