RF frontend functional block

基于rf -MEMS的振荡器，在第一阶段已经得到了基本的概念、数值、实验和技术方法，将向多频率振荡器发展，进一步发展为混合集成MEMS合成器，旨在覆盖相关移动通信标准的广泛分布频谱。对于上UHF范围，间接模拟频率合成似乎是合适的。除了RF-MEMS谐振器（表面波）外，还应比较TP-B2的BAW谐振器（体积波）的频率范围和系统相关特性（特别是相位噪声和温度稳定性）。与项目组C共同在SiCer基板上实现和组装各种电路块，以高质量因素和最小寄生效应为目标。电路设计和布局考虑了项目组a中衍生的方法和模型。进一步的相关活动致力于将MEMS合成器实现、表征和集成到整体多物理MUSIK演示器中。

The RF-MEMS-based oscillator, for which in phase 1 basic conceptional, numerical, experimental, and technological approaches have been derived, shall be developed towards a multi-frequency oscillator and, further on, to a hybrid-integrated MEMS synthesizer, aiming at covering the widely distributed spectrum of relevant mobile communication standards. For the upper UHF range, indirect analog frequency synthesis seems appropriate.Beside RF-MEMS resonators (surface waves), the BAW resonators (volume waves) from TP-B2 shall be compared with respect to frequency range and system relevant properties (especially phase noise and temperature stability). Jointly with the project group C, the various circuit blocks shall be implemented and assembled on a SiCer substrate, aiming at high quality factors and minimal parasitic effects. The circuit design and layout consider the methods and models derived in project group A. Further relevant activities are devoted to the implementation, characterisation, and integration of the MEMS synthesizer into the holistic multi-physical MUSIK demonstrator.
