Conclusion

This book focuses on RF/microwave multimode and reconfigurable filters, systematically introducing their application scenarios, main implementation methods for tunability/reconfigurability, various classifications, and typical performances of reconfigurable filters. It then elaborates, in separate chapters, on the research background, design theories, typical designs, and verifications of multimode bandpass filters, bandwidth-controllable tunable bandpass filters, multi-band tunable bandpass filters, tunable bandstop filters, and other types of tunable filtering devices.
