This paper describes the design and implementation of a filter in the 81-99 GHz frequency band, aimed for the front-end module in a radio astronomy receiver where the image band rejection is very important. Classic formulation is used to design the filter. The fine adjustment process of the filter is based on manufacture considerations through Scattering parameters simulation. Design is based on waveguide resonant cavities topology. Therefore, image band rejection and in band losses are improved compared with micro-strip line technology. Measurements show a flat response with only 0.4 dB insertion losses and 20 dB return loss. Image rejection is very high, 40 dB relative to the pass band.
