摘要 |
A method of producing a microwave filter using a YIG sphere whose resonant frequency is a predetermined function of the temperature is disclosed comprising the steps of introducing a reference YIG sphere with a predetermined orientation into the filter structure and changing the external magnetic field until the resonant frequency is adjusted to a predetermined value. Thereafter another YIG sphere is introduced into the resonator structure and rotated until the resonant frequency is again equal to the predetermined value, whereupon the YIG sphere is locked in position. |
