This paper describes a new original microwave filter design concept using recursive principles and fully integrable in MMIC technology. To validate this technique, a 7 GHz fixed center frequency filter with 2% bandwidth and a tunable filter with 2.5 GHz tuning range around 8 GHz have been successfully implemented employing a 0.2 μm GaAs P‐HEMT monolithic technology. A multicellular approach, using a cascade association of first‐order recursive cells, is also described. A tunable two‐pole filter has then been realized by a cascade association of two tunable one‐pole filters. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 24: 380–385, 2000.
