Highly integrated single package monolithic VCO/up-converter for digital microwave radio systems

It is shown that with state-of-the-art microwave CAD and enhanced active and passive modelling, the concept of a highly integrated low cost macro-function inside a single package can be successfully extended up to microwave frequencies. Simulated and measured results are presented on three integrated VCO/frequency up-converters designed and fabricated at C-, X- and Ku-band frequencies.
