The design and performance of two tuneable GaAs MMIC band stop filters is presented. The first filter was designed to demonstrate the excellent properties of the resonating tank consisting of a varactor diode and a novel active inductor. On the basis of the first filter, a second filter is designed with improved performance, with respect to gain, noise figure and bandwidth. This filter is tuneable from 9 to 11 GHz, with a notch depth of more than 25 dB. The filter exhibits a gain of 4 dB which is flat within 0.5 dB from 6 to 18 GHz. The -10dB notch bandwidth amounts to 60 MHz for a 10 GHz centre frequency. Large-signal behaviour was investigated and hence we believe to report the first fully characterised MMIC tuneable narrow band stop filter at X-band.
