Q-Tech的QT2021系列MCXO晶體振蕩器，具有OCXO級穩定性和高輻射耐受性
QT2021系列微型計算機補償晶體振蕩器（MCXOs）提供在空間應用中，尺寸、重量和功率均優于同類烤箱控制設備。
Q-Tech公司美國領先的太空石英晶體振蕩器供應商宣布推出QT2021系列微型計算機補償晶體振蕩器（MCXOs）。這些新器件提供出色的OCXO級溫度穩定性（在-40°C至+85°C溫度范圍內高達20ppb），同時最大功耗為90mW，比同類OCXO低30個數量級。QT2021系列的主要特點是耐50k rad（Si）TID輻射和75MeV-cm的單粒子閂鎖效應2/mg（分鐘）和高沖擊和振動耐受性，G靈敏度為1 ppb/G . Qt 2021小型封裝僅重50g，相比之下，恒溫晶體振蕩器（OCXO）裝置重100g或更重。這種在尺寸、重量和功率（SWaP）方面的顯著改進為各種先進且要求苛刻的空間應用提供了非常優選的選擇。
Q-Tech的QT2021微型計算機補償晶體振蕩器（MCXO）使用具有微處理器控制補償的高穩定性泛音SC切割晶體。自溫度感應諧振器使用雙模振蕩器，幾乎消除了與溫度測量相關的誤差，從而實現了OCXO級的穩定性。
Q-Tech的市場和銷售總監斯科特·森茨（Scott Sentz）表示:“在21世紀初首次開發MCXO時，空間級和rad硬數字組件非常昂貴，這意味著MCXO空間級產品會非常昂貴。”“應用我們的工程專業知識，通過利用先進的微控制器和其他耐輻射的數字設備，Q-Tech突破了MCXOs空間限制的障礙。”
該系列提供10MHz、20MHz、30MHz、40MHz、50MHz、60MHz和80MHz石英晶振的標準頻率，具有低相位噪聲和抖動的CMOS或正弦波邏輯輸出。

Q-Tech’s QT2021 Series MCXO Crystal Oscillators Deliver OCXO-Level Stability and High Radiation Tolerance
Model QT2021 Series microcomputer-compensated crystal oscillators (MCXOs) deliver superior size, weight, and power over comparable oven-controlled devices for space applications.
Q-Tech Corporation, a US-based leading supplier of space-qualified crystal oscillators, announces the introduction of the QT2021 Series microcomputer compensated crystal oscillators (MCXOs). These new devices provide exceptional OCXO-level temperature stability (up to ±20ppb over -40°C to +85°C) while consuming a maximum of 90mW—thirty orders of magnitude lower than comparable OCXOs. Key features of the QT2021 Series are radiation tolerance to 50kRad(Si) TID, single event latch-up (SEL) of 75MeV-cm2/mg (min) and high shock and vibration tolerance with G-sensitivity of 1ppb/g. The QT2021 small form-factor package weighs just 50g, vs. comparable oven-controlled (OCXO) units weighing 100g or more. This significant improvement in size, weight, and power (SWaP) offers a highly preferable option for a wide array of advanced, and demanding space applications.
Q-Tech’s QT2021 microcomputer compensated crystal oscillator (MCXO) uses a high-stability overtone SC-cut crystal with microprocessor-controlled compensation. The self-temperature sensing resonator, using a dual-mode oscillator, virtually eliminates thermometry-related errors, resulting in OCXO-level stability.
“When MCXOs were first developed in the early 2000s, space- and rad hard-level digital components were very costly, which meant an MCXO space-level product would be prohibitively expensive,” said Scott Sentz, Q-Tech’s Director of Marketing and Sales. “Applying our engineering expertise and by utilizing advanced microcontrollers and other digital devices that are rad tolerant, Q-Tech has broken the barrier of space limitations for MCXOs.”
The series is offered with standard frequencies of 10MHz, 20MHz, 30MHz, 40MHz, 50MHz, 60MHz and 80MHz, with either CMOS or Sine Wave logic outputs with low phase noise and jitter.
