Abstract

The present invention discloses an ultra wide band (UWB) filter with wide stopband. It mainly comprises a first RF signal input/output; a second RF signal input/output; a first attenuation unit; a second attenuation unit; a first resonator and a second resonator. By combining the resonators and attenuation units, the disclosed UWB filter has a wide bandwidth ratio larger than 50% and high bandpass performance. The disclosed UWB filter can be implemented on various types of substrate, suitable for application in UWB system.
