In particular, the quartz crystal resonator (QCR) is a piezoelectric transducer sensitive to the deposition of rigid mass or liquids in contact with its surface (active electrode).
These oscillators have historically been built around a quartz crystal resonator connected to an analog sustaining circuit driving the crystal to vibrate at its resonant frequency.
To prevent direct spitting to the deposition substrate, a 7 mm wide Al beam was inserted between the perforated lid and the substrate of quartz crystal resonator (QCR) separated by 25 mm.
By linking the laser cooling of the crystal resonator with the spin of the internal defect it should be possible to monitor the changes in spin configuration of the internal defect -- these changes are called Bohr spin quantum jumps -- via the mechanical resonator's vibrations.
The Si4901 reportedly removes the requirement for a costly external SRAM, uses DCXO technology to replace external VC-TXCO modules with a low-cost crystal resonator and allows handsets to be made with a phone BOM of less than USD16.
The crystal resonator is the primary factor in maintaining good phase noise performance at the lower supply voltage.
Therefore, using a conventional crystal resonator instead of the TCXO component can reduce the average operating currents in both the receiver and transmitter modes.
The method is based on quartz crystal microbalance (QCM), which allows to detect the mass variation per unit area by measuring the change in frequency of a Quartz Crystal resonator. The device allows the measurement of panel during the production and after being installed (today not possible) in less than one second.
Murata Americas introduced its newest member of the HCR (Hybrid Crystal Resonator) family, the [+ or -] 5Oppm XRCGB-F-N Series.
The extension of the family to cover these frequencies was achieved through the incorporation of a special AT-cut crystal resonator process.
