Narrow Bandpass Filters

Spacek Labs waveguide bandpass iris filters provide excellent RF performance in a small size. These filters are inductive direct-coupled cavity filters. Typical design uses a 0.1 dB ripple Tchebychev response with measured insertion loss of 0.5 to 2 dB (typ) depending on the filter bandwidth and skirt.

When ordering, we will ask you for a specific pass band, what frequencies you would like to reject and  the amount of rejection you would like to achieve.  We can also deliver our waveguide filters with coaxial input and/or output by integrating the transitions from our full line of waveguide to coax adapters.

         

Standard Features:

  • Frequency Bandwidth: 1-13% up to 110 GHz
  • Insertion Loss: 0.5 dB to 3.5 dB max
  • VSWR: 1.5:1 typ

  • Coax input/output available
  • Higher rejection levels available
  • Custom passbands available
