Currently, the increase in demand in microwave devices, for satellite applications, such as rectangular bandpass filters, are due to their better performance and lower manufacturing cost. However, it is necessary to meet with the rigorous technical requirements in band and out of band, such as: lower losses, greater selectivity, greater rejection of higher order resonance frequencies and a wider range of spurious free frequencies. In the present work, the objective is to investigate the aforementioned filters in a rectangular guide, first using the classical topology that is characterized by the use of inductive coupling between the resonators, having a coil as equivalent circuit. Likewise, capacitive coupling will also be used, which has capacitors as an equivalent circuit. On the other hand, both topologies will be used to obtain a hybrid topology (inductive and capacitive windows). Secondly, resonators with stepped impedance will be implemented to attenuate and reject the spurious frequencies of the filter response. Finally, we will be presented hybrid filters of higher order with stepped impedance resonators, with straight and rounded corners, and alternatives for improvements such as folded filters in the planes H and E. For the design of the different topologies of filters in waveguides in the present work, commercial electromagnetic simulation tools (Microwave Office, Fest 3D and HFSS) will be used, which will ensure the convergence of the bandpass filter response.
