Synthétiseur de fréquence à linéarisation de la réponse de la modulation

Frequency synthesizer modulation response linearization

Frequenzsynthetisierer mit Linearisierung des Modulationsganges


In accordance with the present invention, there is provided a method of substantially flattening the modulation response in a frequency synthesizer. The method includes the steps of generating a synthesized frequency F o in response to a filtered control signal V s ; scaling the synthe­ sized frequency F o with a scalar N; generating a control signal I o , having a response substantially the reciprocal of the frequency generation response, and indicative of the phase relationship between a reference frequency F r and the scaled, synthesized frequency F n ; and filtering the control signal, whereby the interaction of the phase relationship control signal response and the frequency generation re­ sponse approximates a flat modulation response.
