Q-Tech超低噪声OCXO满足关键系统的性能需求，AXIOM ULN超低噪声OCXOs

高达GHz频率的AXIOM系列ULN OCXO提供ppb稳定性、超低近载波相位噪声和噪底；为雷达系统、通信和射频测量系统提供基本性能

Q-Tech公司全球领先的空间合格晶体振荡器和高性能频率控制系统供应商宣布推出AXIOM系列超低噪声（ULN）恒温晶体振荡器（OCXOs），该系列由该公司的德国子公司AXTAL设计和制造。超低近载波相位噪声和噪底使雷达系统分辨率更高，通信系统质量更好、传输信息更多，射频测量系统精度更高、测量限值更低。定制版本可提供特定频率和多输出模块。

这AXIOM145ULN非常适合通常需要10MHz OCXOs的通信系统和RF测量系统。该装置的频率温度稳定性为5至20ppb 1Hz偏移时的近载波相位噪声小于-115 dBc/Hz，100kHz时的本底噪声小于-170 dBc/Hz。

雷达和其他类似应用需要从MHz到GHz的频率生成。石英晶振AXIOM75ULN 和 AXIOM5050ULN （80至160MHz）和多路输出AXIOM2700（50MHz至7.0GHz）非常适合这些应用，100Hz偏移时的近载波相位噪声小于-140 dBc/Hz，本底噪声低至-185 dBc/Hz（100MHz载波频率下）。

AXTAL董事总经理Henry Halang表示:“AXTAL不仅提供在宽频率范围内工作的ULN OCXO晶振，还提供使用倍频和/或锁相环（PLL）技术生成GHz信号的整个定制模块。“这些模块完全可定制，为客户提供了最大的设计灵活性。“

Q-Tech进口晶振公司成立于1972年，目标是为要求苛刻的公司提供最先进的晶体时钟振荡器和频率控制解决方案。作为符合MIL-PRF-55310以及超高可靠性标准（如航空航天公司TOR（GPS III）和美国国家航空航天局·GSFC规范）的美国领先产品制造商，Q-Tech自豪地为军事、航空航天、井下和深空行业提供服务。Q-Tech通过了AS9100和ISO 9001质量管理体系认证。该公司的业务遍及全球，销售能力遍及北美、欧洲和亚洲。203年初，Q-Tech完成了对Axtal GmbH & Co KG的收购。对Axtal的收购整合了该公司的产品、欧洲工程开发和ISO9001:2015制造设施。

Press Release – AXIOM ULN Ultra-Low Noise OCXOs

AXTAL Ultra-Low Noise OCXOs Fill Performance Need in Critical Systems

AXIOM Series ULN OCXOs up to GHz frequencies provide ppb stability, ultra-low close-in phase noise and noise floor; deliver essential performance for radar systems, communications and RF measurement systems

Q-Tech Corporation, a leading global supplier of space-qualified crystal oscillators and high-performance frequency control systems, announces the availability of the AXIOM line of ultra-low noise (ULN) oven-controlled crystal oscillators (OCXOs) designed and manufactured by the company’s German affiliate, AXTAL. Ultra-low close-in phase noise and noise floor enable higher resolution for radar systems, better quality and more transmissible information in communications systems and higher accuracy and lower measurement limits in RF measurement systems. Customized versions are available offering specific frequencies and modules with multiple outputs.

The AXIOM145ULN is well suited for communications systems and RF measurement systems that typically require 10 MHz OCXOs. The unit features frequency over temperature stability of 5 to 20 ppb; close-in phase noise of <-115 dBc/Hz @ 1 Hz offset and a noise floor of <-170 dBc/Hz @ ≥100kHz.

Radar and other similar applications require frequency generation from MHz to GHz. The AXIOM75ULN and AXIOM5050ULN (80 to 160 MHz) and multiple output AXIOM2700 (50 MHz to 7.0 GHz) are well suited for these applications, offering close-in phase noise of <-140 dBc/Hz @ 100 Hz offset, and noise floors down to -185 dBc/Hz, respectively (at 100 MHz carrier frequency).

“AXTAL not only offers ULN OCXOs operating over broad frequency ranges, but entire custom modules, which generate GHz signals using frequency multiplication and/or phase-locked loop (PLL) techniques,” said Henry Halang, AXTAL’s Managing Director. “These modules are fully customizable providing customers with maximum design flexibility.”

Q-Tech Corporation was founded in 1972 with the objective of providing state-of-the-art crystal clock oscillators and frequency control solutions for companies with demanding applications. As the leading U.S. manufacturer of qualified products to MIL-PRF-55310 as well as ultra-high reliability standards such as Aerospace Corporation TOR (GPS III) and NASA GSFC specifications, Q-Tech proudly services the military, aerospace, down-hole and deep space industries. Q-Tech is certified to the AS9100 and ISO 9001 Quality Management Systems. The Company maintains a global presence with sales capabilities throughout North America, Europe, and Asia. In early 203, Q-Tech completed the acquisition of Axtal GmbH & Co KG. The Axtal acquisition integrates the company’s products, European-based engineering development and ISO9001:2015 manufacturing facilities.
