High-pass Filters

Standard Features:
  • Frequency Range: 18 to 110 GHz
  • Insertion Loss: 0.2 to 1 dB
  • VSWR: 1.5:1 typ
  • Extremely high rejection

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.
