Abstract

Cavità risonante a microonde a doppio risonatore dielettrico, con frequenza di risonanza sintonizzabile, in cui il risonatore dielettrico principale è chiuso ermeticamente in un supporto di quarzo che sorregge un risonatore dielettrico secondario e lo tiene ad una distanza fissa dal risonatore principale. La sintonia è realizzata tramite una vite metallica a distanza regolabile dal risonatore secondario. Si ottiene una struttura robusta, che minimizza gli effetti negativi delle vibrazioni meccaniche sulla frequenza di risonanza, la cui regolazione risulta lineare con la distanza della vite dal risonatore. Inoltre il fattore di merito Q della cavità rimane costante al variare della frequenza di sintonia (fig. 1).Double dielectric resonator microwave resonant cavity, with tunable resonance frequency, in which the main dielectric resonator is hermetically sealed in a quartz support that supports a secondary dielectric resonator and keeps it at a fixed distance from the main resonator. The tuning is accomplished by means of a metal screw at an adjustable distance from the secondary resonator. A robust structure is obtained, which minimizes the negative effects of mechanical vibrations on the resonance frequency, whose regulation is linear with the distance of the screw from the resonator. Furthermore, the cavity factor Q of the cavity remains constant as the tuning frequency changes (fig. 1).
