The second module was designed as a beamswitch correlation receiver to reduce stability problems. Each feed is followed by a circular polarization transducer. Two adjacent channels are joined by a magic tee. Two cooled MPIfR HEMT amplifiers as first stages and a phase discriminator used as a correlator give the correlation receivers. It features 3 total power outputs with improved stability.
