Abstract


There is an increasing demand for microwave systems to meet the emerging telecommunication challenges with respect to size, performance and cost. This project describes a general design technique for micro strip low pass filters and there optimization that are used to convey microwave frequency signals. The ADS simulation tool is used to design an stepped impedance low pass filter of range 10-14GHz. This simulation results show that the filter works on 10GHz at the center frequency and achieves attenuation of 28dB, which effectively suppresses the parasitic bands. To attain the filter with these characteristics, Insertion Loss Method is performed. Compared to other filter types, this design works very well with excellent harmonic suppression performance.
