该论文提出了一种基于MEMS技术的2.4GHz收发机架构，利用体声波（BAW）谐振器和滤波器实现射频前端的小型化和低功耗。解决了传统无线模块难以集成到微型设备（如助听器、植入式监测器）中的问题。
currently prevent the seamless integration of wireless and networking capability into any tiny high-tech object such as hearing aids or miniature drug delivery monitoring devices or implants. The combination of MEMS technologies, yielding novel devices such as RF bulk acoustic wave (BAW) resonators and filters or low frequency silicon resonators, with RF ICs call for several innovations at the architectural, packaging, circuit and device levels to demonstrate the miniaturization and power reduction potential of the involved technologies [1]. Figure 29.1.1 depicts the architecture of a MEMS-based super-heterodyne transceiver designed in the context of a miniature radio solution for the 2.4GHz ISM band. The main local oscillator is a fixed 2.32GHz or 2.56GHz RF LO based on a high-Q BAW resonator yielding a 30dB improvement in the phase noise times
