Low-pass Filters

Standard Features:
  • Frequency Range: 6 to 110 GHz
  • Bandwidth: 10% to full waveguide bandwidth
  • Insertion Loss: 0.1 to 1 dB
  • VSWR: 1.5:1 typ

Spacek Labs has standard designs for low pass filters covering full waveguide bands in K, Ka and Q bands. We have a library of custom designs up to 110 GHz and we can also design to your specific requirements. These filters can reject out to 5 times the cut-off frequency of the waveguide the filter is designed in. And because the waveguide cut-off is basically a high pass filter these low pass filters work as a bandpass filter.
