The BMCD39 is a 3-channel Ka-band Indoor tracking downconverter. The input filtering is followed by a
two stage downconverter in all channels. The channels are operated from common local sources which have
very good spectral purity. The converter channels are equipped with phase and amplitude control elements in
order to achieve very good phase and amplitude tracking between the channels. The downconverter can be
controlled and monitored via RS-422.
