This paper presents the design and performance of a key RF circuit necessary for the realization of a reconfigurable, integrated RF front-end: a tunable frequency, selectable bandwidth ... Rotator ...

This new filter system uses separate tunable high-pass and low -pass filters in series to define the bandpass. An additional filter is used in series with these filters to provide the best ...

Filtering switches and bandpass filter (BPF) design are critical components ... switch has been developed that features continuously tunable insertion phase and center frequency.
