Abstract

Si combinano 2n segnali ad alta frequenza su una linea unica ininterrotta tramite 2n filtri massimizzando la larghezza della banda e minimizzando la lunghezza della linea con strutture di accoppiamento disposte in coppie di punti dissimetricamente distanziate.Le strutture sono modulari e comprendono, ciascuna, due cavità risonanti, piastre di accoppiamento e cavallotti di scavalco.L'accoppiamento alla linea avviene con due loops lunghi un quarto d'onda.FIG. 2.
