Highhyphen;Qmagnetostatic surface wave planar yttrium iron garnet resonator

摘要

Experimental results on the magnetostatic surface wave resonance characteristics of planar yttrium iron garnet resonators are given. Singlehyphen;mode resonance with wide tunability range and highQhave been achieved.Qas high as 3500 and insertionlossas low as 13 dB with offhyphen;resonance rejection as high as 15 dB have been achieved at 6 GHz. A microwave oscillator built with the resonators and a laboratoryhyphen;made hybrid amplifier provided oscillations in the range 3ndash;5.3 GHz with phase noise of minus;105 dBc/Hz at 10 KHz offsetfromthe carrier frequency.
