In this paper, three topologies of microwave active recursive filters are studied. We show how, using a noise wave formalism, the noise factor of filters can be effectively minimized by using appropriate unbalanced power dividers/combiners and an amplifier. A comparison between the different topologies is given. We validate our approach with simulated examples. © 1998 John Wiley & Sons, Inc. Microwave Opt Technol Lett 18: 269–275, 1998.
