Abstract
A noise reduction filter is inserted between the source and non-linear transmission line (NLTL) in a frequency multiplier to improve phase noise performance. The noise reduction filter is suitably coupled directly to the input of the NLTL. The noise reduction filter and the output BPF are suitably low complexity filters.
