9800B VHF OCXO: Production Results

M. Stanczyk, P. Cash, J. Branch

Abstract:	Microsemi has introduced an updated version of the model 9800B Space Qualified Ovenized Crystal Controlled Oscillator (OCXO). The 9800B is designed for output frequencies of 40 MHz to 125MHz. The updated design provides improved performance for phase noise, temperature stability, short term stability and long term accuracy. The oscillator is a part of the 9600 and 9700 families of oscillators for which more the 400 oscillators have been delivered for military, scientific and commercial satellite applications. In addition to high levels of performance, the 9800 is available in a compact 1.3”x1.3”x1.3” size, requires only 1.3W of quiescent power in vacuum and operates during high levels of shock and vibration. For the 50 MHz variant, phase noise at 10 Hz is typically less than -105 dBc / Hz and Short Term Stability at 10 seconds is less than 5e-12. 9800B’s are available as fixed frequency OCXO’s with an initial accuracy of +/- 2e-7 or as OC/VCXO’s with a tuning range of +/- 3 PPM for fine frequency adjust or for phase lock. This paper will discuss the performance parameters of the 9800B’s built to date.
