The SC5406B from SignalCore is a triple-stage, high-dynamic range, superheterodyne upconverter that converts an input IF frequency of 70 MHz to a tunable RF frequency from 1 MHz to 3.9 GHz. This upconverter has 3rd order linearity and noise performance that rivals direct-conversion devices but without image and in-band LO leakages inherent to them. When paired with a SignalCore downconverter, the pair may form a frequency re-allocator that would receive information on one band and transmit the same information on another band.
The upconverter is available in a module that measures 3.7 x 1.4 x 6.1 inches with SMA female connectors and has a USB and RS-232/SPI communication interface. SignalCore provides full implementation instructions, GUI, driver software, and example code with each module.
