FREQUENCY CHARACTERISTICS OF TWO-POINT FREQUENCY SYNTHESIZERS WITH PHASE DISTORTION COMPENSATION CHANNELS
Authors: Dmitrii Repin, Andrei Lenshin
The transfer functions of functional models of frequency synthesizers (FS) with two-point frequency modulation and distortion compensation channels included in the reference channel, as well as in the feedback circuit of the pulse-phase frequency auto-tuning ring have been developed. Compensation characteristics of FS with distortion compensation channels when using low-pass filters of the 1st and 2nd orders are analyzed.
