Development of ultra low noise VHF OCXO with excellent temperature stability

Abstract

This paper presents development of ultra low noise VHF oven controlled crystal oscillator (OCXO) with excellent temperature stability. The OCXO had the low phase noise less than -170 dBc/Hz at 10 kHz Fourier frequency and the temperature stability within +/-20 ppb in the range of -20 to +70deg.C has been achieved.
