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

Here follows a few of our Ku band filter solutions. We deliver products with high manufacturing and design quality. It is essential that the operation performances are guaranteed.

The required size and weight of the filter solution will often set the bandwidth of operation. ReQuTech has however solutions which are far shorter than the typical industry standards.

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. Here follows a few examples of filters alone as complements to present antenna systems. These filters are delivered with grooves and gaskets with standard flange interfaces or tailored interfaces to fit various Products. If length and dimensions are of importance our engineers will together with our customers find optimal solutions to solve these issues.

Ka band filter examples

Filter type Pass band Reject band Rejection
Receive reject 1 29.00 – 30.00 GHz  19.00 – 21.20 GHz 70 dB
Receive reject 2 30.00 – 31.00 GHz 19.00 – 21.20 GHz 70 dB
Transmit reject 1 19.20 – 20.20 GHz 29.00 – 30.00 GHz 70 dB
Transmit reject 2 20.20 – 21.20 GHz 30.00 – 31.00 GHz 70 dB

C band filters

We deliver C band filters together with our standard 1.8m band 2.2 m segmented antenna systems. However it is of course also possible to tailor a standalone filter solution based on excising antenna systems.

C band filter examples

Filter type Pass band Reject band Rejection
Receive reject 5.85 – 6.43 GHz 3.60 – 4.20 GHz 70 dB
Transmit reject 3.60 – 4.20 GHz 5.85 – 6.43 GHz 70 dB
