摘要

介绍了一种工作频率为433.92 MHz的低噪声SAW振荡器的设计和性能。在输出功率为11 dBm时，振荡器显示出在1 kHz偏置下的单边带载波噪声比为6f 125 dBc/Hz。用Leesons模型计算的振荡器相位噪声与实测数据吻合较好。对温度稳定性、谐波和杂散信号进行评价。

A Low Phase Noise 433.92 Mhz Saw Oscillator for General Mobile Communication Applications

The design and the performance of a low noise SAW oscillator operating at 433.92 MHz are presented. At a power output of 11 dBm the oscillator shows a single sideband phase noise to carrier ratio 6f 125 dBc/Hz at 1 kHz offset. Calculations of the oscillator phase noise using Leesons model agree well with measured data. Comments will be given on temperature stability, harmonics and spurious signals.
