Crystal Resonators

Crystal resonators are used in many applications, including in-dash personal navigational devices; microwave backhaul networks; smart phones; tablets; GPS modules and g-sensitive defence equipment.

The natural properties of quartz generate a high Q piezo electric effect and, when cut and dimensioned correctly, offer several orders of magnitude better stability than silicon. The high Q of quartz also enables the manufacturing of lower phase noise oscillators essential for high bandwidth communications. Silicon MEMS oscillators aim to mimic this using complex MEMS processing to compensate for the poorer properties of silicon, combined with multiple noise-adding and costly phase-locked loops.

Rakon’s XMEMS™ crystals are manufactured using its NanoQuartz™ process. This process achieves critical quartz dimension accuracies in the tens of nanometre range. This allows  control of key resonator properties such as Q, frequency stability and unwanted modes to unprecedented levels.
