Abstract :
A novel GaAs MMIC active filter structure based on the lumped and transversal technique is proposed for operation in the X-band. This new structure includes a tuned amplifier in order to improve the band edge rejection. A design example of a bandpass filter centered @ 7.5 GHz with 2 dB passband ripple and 30 dB rejection @1 GHz apart from passband edges is presented in terms of computer simulated results and layout. The simulated results demonstrate its superior performance when compared with the traditional lumped and transversal technique
