Filters for C, Ku, Ka band

ReQuTech designs and manufactures high quality microwave filters for satcom and telecom frequency bands.
Present solutions range from C, X, Ku and Ka band filters for Transmit and Receive filtering. Below follows a few designs for Ku, Ka and C band operations.

Ku band filters

ReQuTech offers a wide range of Ku band filter solutions. Our filters are shorter and lighter weight than industry standards, ideal for weight or space limited applications such as manpacks or antennas under radomes.

All ReQuTech filters are made to the highest design and manufacturing standards to guaranteed operational performance levels.

The table below shows some examples. Please contact us if you don’t see what you need.

Ku band filter examples

Filter type Pass band Reject band Rejection
Receive reject 1 12.75-13.25 GHz  until 12.25 GHz 70 dB
Receive reject 2 13.75-14.50 GHz 10.70 – 12.75 GHz 70 dB
Transmit reject 1 10.75 – 12.25 GHz 13.75 – 14.50 GHz 70 dB
Transmit reject 2 10.70 – 10.95 GHz 13.00 – 13.25 GHz 70 dB
Transmit reject 3 10.70 – 12.75 GHz 13.75 – 14.50 GHz 70 dB

Ka band filters

ReQuTech delivers full feed systems including transmit and receive reject filters. Our filters are available as stand-alone components with grooves for gaskets/O-rings. They can be made with standard flange interfaces or can be tailored to interface with your systems. We also offer fully tailored filters to provide optimal solutions to your dimensional and performance requirements.
