Rohde & Schwarz has released a 40 GHz version of its SGU100A RF upconverter. This version expands the frequency range of the SGS100A vector signal generator from 12.75 GHz to 40 GHz, making it the smallest microwave device of its kind on the market for continuous signals between 80 MHz and 40 GHz.
Though compact (two height units and ½ 19in rack width or one height unit and full 19in rack width ), the combination of the upconverter and vector signal generator offers outstanding performance. The setup is perfectly suited for ultra-wideband aerospace and defence applications, as starting from 12 GHz the upconverter can be used with a 2 GHz I/Q modulation bandwidth.
Together with the vector signal generator and its frequency range of up to 40 GHz, a compact system with a maximum of three phase coherent outputs up to 40 GHz can be set up that can test phased array antenna systems.
The R&S SGU100A is now available from Rohde & Schwarz as a pure CW upconverter and as a version for I/Q-modulated signals.
