Here we present the design of a receiver that will cover the frequency range from 31 to 45 GHz. The receiver will use a horn and a lens to couple the incoming radiation into the waveguide structure. Then, an orthomode transducer will split the signal in two polarizations. Each one of them is then amplified and down converted using the upper sideband mixing scheme. The results of the electromagnetic modeling of every component are also presented here. We also discuss how the components will be implemented.
