Reconfigurable filters are key components in the development of agile multi-standard receivers. The advent of innovative switched capacitor arrays and switch technologies based on Silicon on Sapphire, Micro-Electro-Mechanical Systems (MEMS) and Phase Change Material (PCM) technologies permits the development of a new generation of high linearity, low loss, and low power consumption tunable components. In this new generation of reconfigurable microwave front-ends, microwave reconfigurable filters are among the most critical and challenging components to perform adaptive frequency-band selection. This DML talk starts by addressing the needs for using multi-band and tunable filters in wireless communication systems and in flexible satellite payloads. It then addresses existing tuning technologies, providing a comparison between piezoelectric, Semiconductor, MEMS and PCM tuning elements in terms of linearity, insertion loss, suitability for use at millimeter-wave frequencies and ease of integration with high-Q filters. It outlines major design considerations for tunable filters presenting techniques to realize tunable filters with an absolute constant absolute bandwidth and a constant frequency spacing between transmission zeros, over a wide tuning range. The talk also illustrates examples of tunable filters and diplexers tuned only a by single tuning element, while exhibiting a constant absolute bandwidth. It then addresses approaches for realizing multi-band filters including dual-band and triple-band filters. Finally, it presents techniques for realizing multi-band filters where the various bands are tunable in both center frequency and bandwidth.
