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).
