In today’s dynamic space environment, where precision and reliability are paramount, AXTAL GmbH introduces its state-of-the-art temperature-compensated crystal oscillators (TCXOs) and oven-controlled crystal oscillators (OCXOs). These devices have been designed to meet the demanding mission-critical requirements of space. They provide outstanding radiation immunity and frequency stability for LEO applications and pave the way for lower-cost, high performance space solutions.


AXTAL’s TCXOs set new standards with their compact design and exceptional stability. The AXLE7050S and AXLE5032S series fulfill this requirement at frequencies from 10 to 50 MHz with stabilities up to ±1 ppm. They are designed and tested to withstand radiation levels of up to 40 kRad(Si) TID and are immune to single-event latch-ups up to 120 MeV-cm2/mg. With typical phase noise levels of -67 dBc/Hz at 1 Hz and a floor of -160 dBc/Hz (20 MHz), they guarantee precise timing for critical space missions. The AXLE7050S and AXLE5032S are packaged in hermetically sealed, surface-mount ceramic enclosures measuring 7 x 5 mm and 5 x 3.2 mm, respectively, offering versatility without compromise.


For applications requiring higher stability, AXTAL’s OCXOs operate flawlessly in high-radiation environments and offer precision in every aspect. The AXIOM70SL, AXIOM75SL, AXIOM3838S (10 MHz) and AXIOM75SH (100 MHz) series set new standards with their ±10 ppb (10 MHz) stability and robust construction. With typical phase noise levels of -135 dBc/Hz at 100 Hz and a floor of -180 dBc/Hz (100 MHz), they ensure uncompromising performance. These OCXOs are available in various sizes and configurations from 25 x 25 mm THD/SMD to 38 x 38 mm connectorized and offer unrivaled flexibility for various space applications.

With its continued commitment to innovation and quality, AXTAL pushes the boundaries of space technology to ensure the success of future space projects.
