本文提出了一种利用悬置带状线谐振器设计可调谐振荡器的新方法。将负阻场效应晶体管（FET）安装在微带线（MSL）上，与高Q值悬置带状线（SSL）谐振器相结合，构成一种相位噪声良好的可调谐振荡器。新的MSL到SSL转换有助于基于MSL的电路和SSL模块之间的轻松连接。所提出的振荡器也是频率可调谐的使用调谐器位于顶部的SSL外壳。在125.7 MHz频率调谐下，所实现的振荡器在5.148 GHz处的实测相位噪声为-104.34 dBc@100 kHz和-133.21 dBc@1 MHz。
In this paper, a new design method of a tunable oscillator using a suspended-stripline resonator is presented. The negative resistance of an FET mounted on microstrip line (MSL) is combined with a high Q suspended-stripline (SSL) resonator to produce a tunable oscillator with good phase noise. The new MSL-to-SSL transition facilitates easy connection between the MSL-based circuits and the SSL module. The proposed oscillator is also frequency-tunable using a tuner located on the top of the SSL housing. The measured phase noise of the implemented oscillator at 5.148 GHz is -104.34 dBc@100 kHz and -133.21 dBc@1 MHz with 125.7 MHz of frequency tuning.
