Low-pass Filters

Spacek Labs has standard designs for low pass filters covering full waveguide bands in K through W band. 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. Due to waveguide cut-off, which is basically a high pass filter, these low pass filters can be considered bandpass filters.

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.
