Active Multipliers and Dividers to Simplify Synthesizers

A new family of active frequency multipliers and dividers is featured this month
Modern frequency synthesis uses a combination of frequency multiplication and frequency division to generate the required data and carrier signals for microwave radio and radar applications. Frequency multiplication increases the carrier frequency while increasing the phase noise of the carrier by 20log(N), where N is the multiplication factor. Conversely,...
