Abstract

Si descrive un combinatore di segnali a frequenze elevate (nel campo delle microonde, in particolare, dal centinaio di Megahertz alle decine di Gigahertz), nel quale il rapporto fra le potenze dei segnali che giungono alla porta di uscita e provengono da due diverse porte di ingresso può essere variato con continuità, detto combinatore comprendono almeno tre ibridi ad es. a 3dB/90°, (ABC), un doppio corto circuito fisso (E), un carico (G) e un doppio corto circuito mobile (F) con linea di lunghezza L variabile da 0 a >/4, essendo la lunghezza d'onda corrispondente alla frequenza centrale della banda. Esso è ora caratterizzato da un T-magico e da un doppio corto circuito mobile su linee ciascuna costituita da due tratte di lunghezza L= >/4.(Fig. 4)
