Abstract:
A method for characterizing a frequency response of a resonant cavity filter comprising a cavity, a dielectric resonator disposed in the cavity, and a tuning element moveable within the cavity relative to the dielectric resonator, the method comprising the steps of:(a) inputting an input signal having a first frequency to the resonant cavity filter;(b) moving the tuning element relative to the dielectric resonator until the resonant cavity filter resonates at said first frequency;(c) storing information in electronic memory representing a position of movement of the tuning element relative to the dielectric resonator corresponding to the first frequency; and(d) repeating steps (a), (b) and (c) for a plurality of frequencies across a range of frequencies for which it is desired to know the frequency response of the resonant cavity filter.
