The company coftech GMBH has been supplying high quality quartz components for more than 40 years now. Our main focus lies in providing customer-oriented solutions and competent technical advice with regard to quartz, oscillators, quartz filters, SAW products and antennas. Our partner QuartzCom, Switzerland, produces TCXO and VCTCXO, where a high frequency stability, low phase noise, resistance to vibration and shock resistance as well as low G sensitivity or a low hysteresis are essential for the clock signal.
Using the types 7.0 x 5.0 mm and 5.0 x 3.2 mm we achieve frequency stabilities of ± 0.2 ppm (higher than -40 to + 85 ° C), on request even ± 0.1 ppm. A typical value for a low G sensitivity is 1x10-10 / g and for the total frequency stability within 20 years of ± 4.6ppm (higher than -40 to + 85 ° C). Besides the serial production, we also deliver small quantities within 6 to 8 weeks.
These reference clock requirements are found in applications such as professional mobile radio, measuring devices, COSPAS-SARSAT, femtocell, aeronautical radio, broadcasting, satellite navigation (GNSS) and train radio.
