Bandpass and Bandpass Harmonic Filters

Band Pass Filters
 

  • Design uses single, double, and triple E-plane metal inserts for size and power handling requiremnets
  • Resonators of different lenghts and widths achieve excellent in band and out-of-band response
  • Evanescent-mode serrated single ridge technique for small filters with extremely wide stopband
