Q-Tech超低噪聲OCXO滿足關鍵系統的性能需求，AXIOM ULN超低噪聲OCXOs
高達GHz頻率的AXIOM系列ULN OCXO提供ppb穩定性、超低近載波相位噪聲和噪底；為雷達系統、通信和射頻測量系統提供基本性能
Q-Tech公司全球領先的空間合格晶體振蕩器和高性能頻率控制系統供應商宣布推出AXIOM系列超低噪聲（ULN）恒溫晶體振蕩器（OCXOs），該系列由該公司的德國子公司AXTAL設計和制造。超低近載波相位噪聲和噪底使雷達系統分辨率更高，通信系統質量更好、傳輸信息更多，射頻測量系統精度更高、測量限值更低。定制版本可提供特定頻率和多輸出模塊。
這AXIOM145ULN非常適合通常需要10MHz OCXOs的通信系統和RF測量系統。該裝置的頻率溫度穩定性為5至20ppb 1Hz偏移時的近載波相位噪聲小于-115 dBc/Hz，100kHz時的本底噪聲小于-170 dBc/Hz。
雷達和其他類似應用需要從MHz到GHz的頻率生成。石英晶振AXIOM75ULN 和 AXIOM5050ULN （80至160MHz）和多路輸出AXIOM2700
AXTAL董事總經理Henry Halang表示:“AXTAL不僅提供在寬頻率范圍內工作的ULN OCXO晶振，還提供使用倍頻和/或鎖相環（PLL）技術生成GHz信號的整個定制模塊。“這些模塊完全可定制，為客戶提供了最大的設計靈活性。“
Q-Tech進口晶振公司成立于1972年，目標是為要求苛刻的公司提供最先進的晶體時鐘振蕩器和頻率控制解決方案。作為符合MIL-PRF-55310以及超高可靠性標準（如航空航天公司TOR（GPS III）和美國國家航空航天局·GSFC規范）的美國領先產品制造商，Q-Tech自豪地為軍事、航空航天、井下和深空行業提供服務。Q-Tech通過了AS9100和ISO 9001質量管理體系認證。該公司的業務遍及全球，銷售能力遍及北美、歐洲和亞洲。203年初，Q-Tech完成了對Axtal GmbH & Co KG的收購。對Axtal的收購整合了該公司的產品、歐洲工程開發和ISO9001:2015制造設施。

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.
