Abstract :
A novel microwave active bandpass filter has been designed in a coplanar waveguide. The approach uses a GaAs FET to link two end-coupled resonators. The realised active filter not only compensates for the losses as compared to a passive filter but also provides an overall gain of 17.54 dB. Flexibility in tuning the filter response through the bias voltage and its superior performance at the harmonics over the passive filters are among the advantages of the design
