摘　　要：本文讨论了声表面波压控(调频)振荡器的原理及设计方法,并实际制作了振荡器,中心频率为657MHz,频偏约为1.5×10^(-3),平均压控灵敏度为98kHz/V,线性度±2%,温度稳定度为±3.7×10^(-5)(-20—+60℃)。This paper described the principle of voltage-controlled SAW oscillator and the design, method. A oscillator with centre frequency 657MHz has been fab-ricated.Its frequency deviation is 1.5×10-3, average voltage-controlled sensitivity is 98kHz/V,linearity is ±2%; and the temperature stability is ± 3.7XKT-5 in the range of-20℃-60℃
