Bascom Hunter’s Miniature Quartet Frequency Converter (MQFC) is designed for demanding environmental requirements. Its small, but robust form factor makes it ideal for rugged ground vehicles. The unit operates at tune frequencies from 2 to 18 GHz with 500MHz of instantaneous bandwidth. All 4 channels have left and right inputs for use with multiple inputs, are fully phase coherent, and provide well matched conversion paths for optimal operation.
