Frequency control specialist Euroquartz has announced availability of three new ranges of ultra-miniature quartz crystals from Statek that are designed for use in medical-implantable wireless RF transceiver applications using Bluetooth Low-Energy (BLE) or Medical Implant Communications Service (MICS) specifications.
The CX16, CX18 and CX20 series are ultra-miniature devices operating in the 16MHz and above frequency range requested by BLE transceiver ICs. In medical applications, where miniaturisation is paramount Statek’s, low profile CX16 AT quartz crystal is the ideal choice, measuring 2.0mm x 1.2mm and just 0.43mm high. Offering frequencies from 24MHz to 50MHz, the CX16’s resonator is manufactured using state-of-the-art photolithographic and chemical milling processes then sealed in a ceramic package for high-stability and low-ageing. CX16 crystals are available with tight calibration tolerances and high-stability over temperature, as well as fast start-up times.
Medical applications include medical telemetry, pacemakers, defibrillators, neurostimulators, infusion pumps and cochlear implants. Additional characteristics include high-shock and vibration survival with full military testing also available for defence and aerospace applications.
Smaller still is the CX18 series measuring 1.6mm x 1mm x 0.38mm and offering frequencies from 30MHz to 50MHz. With its ultra-light weight of just 1.8mg, the CX18 series is suited to similar medical applications as the CX16, as well as military and aerospace applications such as missile telemetry, ruggedised communications, aircraft electronics and smart munitions with full military screening available. CX18 series crystals are also suitable for a range of industrial and communications applications such as bio-tracking, process control and portable instrumentation.
Statek CX20 telemetry crystals have footprint of 2.5mm x 1.2mm and height of 0.5mm with frequency range from 16MHz to 50MHz. Applications encompass ultra-low power wireless communications, implantable transceivers for medical sector with smart munitions, guidance and navigation and communications in military and defence. These crystals can also be used in industrial communications, transmitters, pulse generators, tracking beacons and wildlife telemetry.
All three ranges are available with commercial (-10°C to 70°C), industrial (-40°C to 80°C) and military (-55°C to 125°C) operating temperature ranges with packaging options of tray pack and 12mm tape and reel (8mm for CX16).
