Abstract

A Microstrip structure for IF signal filtering for Direct to Home (DTH) application is reported in this paper. The filter design hinges on cascaded cross coupled trisection open loop resonators. The filter is designed and simulated using ADS tool. The filter provides a bandwidth of 240 MHz, with a center frequency of 1.32 GHz. The novelty of this paper lies in its improved Fractional Bandwidth (FBW) and in the context of application of the filter, wherein a simple and compact design is adapted for DTH application. The response of the fabricated filter is found to agree with the simulation.
