Popis:	A new topology of active bandstop filters is proposed in this paper. Two prototypes based on this topology have been implemented: the first one in GaN technology and the second one in GaAs technology. This topology allows reducing the 3 dB bandwidth in comparison with the only passive cell. The structure of both filters is a distributed structure. The first one allows a rejection of 65 dB at 2.9 GHz and the second one allows three states with a rejection around 45 dB at 2.3 GHz (state 1), at 2.47 GHz (state 2) and at 2.87 GHz (state 3). Both have associated passband from 1 GHz to 18 GHz.
