Abstract :
This review paper presents recent developments in high-Q three-dimensional tunable filters tuned by piezomotors, MEMS and semiconductor elements for wireless base station applications. It also addresses main challenges in designing tunable filters with an absolute constant bandwidth and a constant Q over the tuning range. Experimental results are presented for a wide range of tunable bandpass filters.
