摘　　要：介绍了高稳定声表面波SZD817型振荡器,它具有优良的频率温度稳定特性,体积小(50mm×30mm×18mm),质量轻(小于50g),相位噪声低,谐波和杂波抑制高,工作温度范围宽(-55～+85°C),可靠性高等特点。一般声表面波振荡器的频率温度稳定性都在10-4量级以上。而SZD817型振荡器的频率温度稳定性,在工作温度-55～+85°C情况下为10-6量级,在-40～+70°C情况下达10-7量级。A highly stable SAW oscillator is introduced in the paper. This SZD817 model oscillator is characterized with excellent temperature stability, low phase noise and high rejection of harmonic and clutter suppression. The device is also small (50 mm×30 mm×18 mm) and light (<50 g) with wide working temperature ranging from -55 °C to +85°C. Normally the frequency-temperature stability for oscillator is in the order of 10^(-4), but for above said oscillator, the stability is 10^(-6) at -55 °C to +85 °C while 10^(-7) at -40 °C to 70 °C.
