The iDC-3743 Block Downconverter covers 37-40GHz and 40-43GHz vertical and horizontal polarizations. Frequency range is switch selectable on the front of the unit. The low SWAP allows for mounting directly to the antenna feed. The iDC-3743 provides an extremely low noise figure and phase noise to receive and ultimately process high order digital modulation waveforms. Two or more downconverters are capable of being synchronized via an external 10MHz reference.
