Stripline bandpass filters with step-impedance resonators

  • 75 Accesses

  • 5 Citations


Research results for stripline bandpass filters with step-impedance resonators formed on Al2O3 (Alumina, polycor) and operating in the frequency band 1500–2500 MHz are presented in this article. Use of step-impedance resonators breaks repetition factor in frequency positioning of passbands in such filters. This allows suppressing harmonics of output signal in transmitters and widening stopband for parasitic signals in receivers.
