摘　　要：提出了VCOCXO的一种新型控温方法 ,论述了其控温原理及实现 .从而研制成频率温度稳定度达到± 1× 10 -8( - 40～ 70℃ ) ,体积为 2 5mm× 2 5mm×A method of temperature control for VCOCXO was presen te d to develop a small VCOCXO with relatively high stability based on single oven structure through delicate designing of the oscillating, temperature control cir cuit and the oven structure. The experiment results indicated that the proposed VCOXCO had a ±1×10 -8 frequency stability and temperature range from -4 0?℃ to 70?℃.
