Must
Read Papers:
1.51-GHz with Q
>10,000 Even in Air!
A result of
purposely impedance-mismatching a polydiamond disk with its polysilicon stem.
1.2-GHz with Q = 14,600!
Who says diamond is needed to get Q
>10,000 at GHz frequencies? With the right "hollow-disk" ring
design, polysilicon can do even better than diamond.
60-MHz Wine-Glass Disk Oscillator Makes
the GSM Reference Oscillator Spec!
Higher power
handling and a Q >50,000 crucial in making the spec.
Arraying for Impedance <480W at 72MHz!
Mechanically
coupled resonator arrays automatically align resonator frequencies to allow
output summation for low impedance and higher power handling.
