A novel systematic and consistent method for twobranch channelized active bandpass filter design is presented. The
design technique is obtained starting from a rigorous and detailed theoretic analysis of this type of filter, nondeveloped to date. In the proposed method, the values of key design parameters are established directly from the initial specifications by using a simple set of design formulas. The design procedure is validated with construction and measurement of a specific two-branch channelized filter prototype at 2.5 GHz in microstrip technology. Other relevant factors in active filter design techniques, such as nonlinear and noise performance, are also considered in the experimental characterization
of the filter prototype.
