NI’s custom, fast-settling, low phase noise DTOs use high-performance Si BJTs and silicon varactor diodes to realize multiple wideband sources, which are combined using Wilkinson power combiners. GaAs MMIC buffer amplifiers provide the necessary power output and load isolation of the oscillator. Efficient use of EEPROMs yields high accuracy, high resolution, and high linearity. In addtion, a proprietary technique is used to achieve fast switching and low spurious. DTOs are available in frequencies up to 67 GHz. Please note that we only accept orders with minimum quantities of 100 pieces.
