In this article, an UHF third order bandpass filter based on an high‐Q active inductor (AI) is described and measurement results, performed on a prototype board, are presented and compared with software simulations. The designed AI includes a passive variable phase‐ and amplitude‐compensating network and a highly linear inverting amplifier, forming a gyrator‐C architecture that gives to the filter also frequency and amplitude tuneability proprieties. The fabricated Butterworth filter has a center frequency of 600 MHz and a measured noise figure of 11 dB with a 5 dBm 1‐dB compression point and a 82 dB dynamic range. All passive components values have been chosen to allow the circuit to be completely integrated in a standard IC design. © 2012 Wiley Periodicals, Inc.
