Pengayun kristal kawalan ketuhar (OCXO) yang sangat stabil dengan ciri hingar fasa rendah telah dibangunkan menggunakan pengayun kristal kuarza potongan SC dua mod. OCXO menggunakan sistem kawalan ketuhar konvensional untuk pampasan kasar dan sistem pembetulan digital, yang menggunakan isyarat mod B dalam resonator potong SC sebagai penderia suhu, untuk pampasan yang baik. Menggabungkan kedua-dua bentuk pampasan ini sangat meningkatkan kestabilan frekuensi mod C tanpa memerlukan sistem ketuhar dua kali. Keputusan eksperimen menunjukkan bahawa kestabilan frekuensi OCXO yang dicadangkan, termasuk histeresis suhu frekuensi, adalah sepuluh kali lebih baik daripada OCXO yang berjalan bebas konvensional. Keputusan juga menunjukkan bahawa OCXO yang dicadangkan mempunyai kebolehjejak semula frekuensi yang baik dan ciri-ciri hingar fasa rendah.

Abstract: A highly stable oven-controlled crystal oscillator (OCXO) with low phase-noise characteristics has been developed using a dual-mode SC-cut quartz crystal oscillator. The OCXO uses a conventional oven-control system for coarse compensation and a digital-correction system, which uses B-mode signal in an SC-cut resonator as a temperature sensor, for fine compensation. Combining these two forms of compensation greatly improves the stability of the C-mode frequency without requiring a double-oven system. The experimental results indicated that the frequency stability of the proposed OCXO, including the frequency-temperature hysteresis, is ten times better than that of a conventional, free-running OCXO. The results also indicated that the proposed OCXO has good frequency retraceability and low phase-noise characteristics.
