An overview is given for the current state-of-the-art of semiconductor based tunable RF elements. For this purpose, semiconductor based capacitive switch banks and varactors are reviewed and compared with the recently developed ultra-low distortion semiconductor based varactors. It reveals that the latter solution, when compared against all existing technology platforms for continuously tunable elements, can provide superior performance in tuning range, linearity, and quality factor.
