摘要
声体波谐振器(FBAR)压控振荡器(VCO)技术探讨了高品质因数Q谐振器并实现宽频率调谐难题,完成了声体波谐振器MBVD模型参数建立、电路的选择与布局,以及最优化的设计与制作,尽量消除了FBAR与IC之间的引线产生的影响,克服了频率调整问题。研制了中心频率2.1GHz的VCO振荡器,研究结果表明,其输出功率为5~10dBm,调谐范围为2.044‰,边带相噪为-143dBc/1Hz@1MHz。
A high Q resonator and its tuning in a wide frequency range have been realized by using the BAW resonator VCO technology. The selection of MBVD model parameters of BAW resonator has been done. The selection and layout of the circuit have been arranged and the design and fabrication of the device have been optimized. The influence due to the bonding wire between the FBAR and IC has been eliminated and the frequency adjustment has been avoided. A VCO oscillator with the central frequency of 2.1 GHz has been developed, its output power is up to 5-10 dBm, the tuning range up to 2. 044‰, the sideband phase noise up to -143 dBc/1 Hz@1 MHz.
