All the receivers the first section of low noise amplifier(LNA) is presided by input filter. It is mainly required to restrict the input noise to the LNA. This filter should have very low insertion loss very good return loss and sufficient out of band attenuation for suppressing the interference. In this paper input filter design for frontend satellite navigation receiver at L-S Band has been presented. The filter design is based of chebyshev characteristics. In this paper we propose a Chebyshev Band pass filter for 1.1 GHz&2.5 GHz application using Advanced design software. The filter is operated at L band frequency range in 1.1 GHz &S band frequency range in 2.5 GHz for applications of front end receiver which is similar to Indian regional navigation satellite system(IRNSS).The proposed filter is design at a center frequency of 1.8 GHz. Simulation results show that the filter operation is optimum over the frequency range 1.1 GHz to 2.5 GHz which is best in this range.
