A compact tune-all bandpass filter is presented. This electronically tuned filter is based on series-coupled slow-wave resonators. It allows wide simultaneous and continuous tunings of centre frequency (+/-15% around 0.7 GHz) and bandwidth (from 50 to 100 MHz) with insertion loss IL < 5.4 dB and return loss RL > 11 dB. This two-pole bandpass filter exhibits also a very small surface of only 7.3 10^-3 lambda0^2 and a -20 dB stop-band that extends up to 10 GHz.
