  • Abstract
    A miniature low power oscillator has been developed to meet the frequency and timing requirements of a man-portable satellite terminal. Based on the existing Q-Tech MCXO (microprocessor controlled crystal oscillator), the QT2001, which has been extensively discussed in previous papers, provides a frequency-temperature accuracy of +/- 3E-8. Features added in this development effort include outputs at 200 MHz, 100 MHz, and 50 MHz, reduced output spectrum spurious frequency levels to -70 dBC @ 200 MHz, a real-time clock with RS232 interface, and a 5 mW time keeping `Watch´ mode
