This paper discusses use of MEMS technologies in radio frequency (RF) frontend. First, configuration of RF front-end in current wireless communication systems is surveyed, and research trends of the flexible RF front-end and software defined radio (SDR) are discussed. Second, various RF tunable filters are introduced, and we discuss how high performances are expected by the use of tunable RF surface and bulk acoustic wave (SAW/BAW) filters provided that above mentioned key technologies are developed. Finally, our attempts for realization of tunable RF SAW/BAW filters are introduced.

Run Up

Low power and portable systems working at high frequency are becoming a significant force in the communication industry. SAW filters have been used in wireless communication systems since the early days of mobile phones. But applications at the higher handset frequencies run up against the capability of conventional SAW structures. Bulk Acoustic Wave (BAW) Technology, a relatively recent addition to this portfolio follows MEMS principle to design high performance microwave components for RF communication. Simulation of the Bulk Acoustic Resonator using Butterworth Van Dyke Model (BVD) Model and design of Ladder Filter with the designed resonator in the RF design platform Agilent ADS (Advanced Design System) have been presented. The simulated results confirm the tuning of operating frequency of designed BAW device at 2.4 GHz.

Design Challenges

Next generation wireless systems support a wide range of communication protocols and services, opening new design challenges. The desired flexibility presupposes effective approaches that exploit the system configurations with an optimal way. A well-known state-of-the-art example of a wireless platform is the Software Defined Radio (SDR). SDRs are characterized by strict performance requirements that introduce a lot of dynamism in respect with the resource utilization. Additionally, these devices experience transient overloads due to workload bursts or hardware malfunctions. The aforementioned reasons lead the system to take timely reactions to unexpected usage scenarios. The current chapter concentrates on these design challenges exploiting the system scenario methodology, proposing solutions especially for wireless communication systems. More precisely, it will be studied the tradeoffs between the representativeness of the scenarios (clustering overhead), the implementation of the scenario detection (detection overhead) and the platform tuning cost (switching overhead).
