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.
