Multiloop microwave frequency synthesizer with low phase noise

摘要

Multiloop microwave frequency synthesizer especially suited as a local oscillator in low capacity transmission systems comprising essentially a microwave frequency synthesizer loop (1), a wide step programmable frequency synthesizer loop (2) and a fine step programmable frequency synthesizer loop (3) provided and interconnected in a particularly efficient manner to obtain low phase noise, high frequency jump immunity, low cost and small space occupied.
