In this paper, by using the concept of microstrip lines we have designed parallel edge coupled band pass filter which can be implemented on various RF/microwave applications. The design is simplified by beginning with low-pass filter prototypes that are normalized in terms of impedance and frequency. Transformations are then applied to convert the prototype designs to the desired frequency range and impedance level. Order of the filter determines the number of reactive elements needed for the filter design. As we go on increasing the order of the filter, it helps us to reach the ideal response of the filter. The choice of order of the filter is made to ease implementation. The implementation of transmission line filters is based on characteristics impedance changes. Higher the order of filter, the difficult the required changes in characteristics impedance become, however the performance of a filter improves with an order increase. Advanced design system (ADS) simulation software from Agilent technologies is used to simulate filters designed for different frequencies and using electromagnetic (EM) simulation tools, to predict the performance of the filter structure. The advantage of using microstrip line filter is that, as the frequency increases the reactance of the lumped components (inductors and capacitors) varies or not constant, so it is not possible to maintain the proper characteristics of the filter at higher frequencies. So, in order to overcome this difficulty, it’s better to use microstrip line filter. A good way of designing microstrip filter aiding by ADS which shows feasible in practice and features in low cost, simple structure and applicability in radio receiver. The optimization function owing by ADS is an efficient tool to amend the drawback of the conventional method with theoretical formulas.
