Abstract :
This paper deals with the design of the RF front-end building blocks, particularly with a digitally tunable input filter for agile communication standards within LTE bands. The initial design of the tunable filter unit is described and its tuning capabilities are verified by simulations. The filter tuning ability between frequencies from 1.7 GHz up to 2.17GHz is demonstrated.
