Design of broadband, highly integrated, 20-30 GHz and 35-45 GHz MMIC up-converters

The design of broadband, highly integrated up-converters is described. Two up-converters have been designed to reduce the complexity and cost of broadband millimetre wave systems by integrating a number of functions into a compact MMIC. Broadband performance was achieved for 20-30 GHz and 35-45 GHz with OIP3 exceeding 24 and 15 dBm, respectively; 2xLO leakage better than 3 dBm and excellent gain control. To our knowledge, this is the highest level of integration achieved for an up-converter at these frequencies.
