High-pass Filters

Spacek Labs High Pass Filters are very effective, reliable and accurate at cutting off frequencies below the desired bandwidth. These filters use cut-off waveguide at a length equal to an integral number of half wavelengths of the center passband. For improved insertion loss and VSWR the reject frequency should be about 5-10% lower than the lowest pass frequency.


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 Range: 18 to 110 GHz
  • Insertion Loss: 0.5 to 2.5 dB
  • VSWR: 1.5:1 typ

  • Extremely high rejection
  • Coaxial High-pass Filters also available
  • Higher rejection levels available
  • Custom passbands available
