METHOD AND DEVICE TO DEMODULATE AMPLITUDE-MODULATED RF-SIGNALS Russian patent published in 2009 - IPC H03D1/12 

Abstract RU 2366075 C1

FIELD: radio engineering and communication.

SUBSTANCE: invention relates to radio engineering and communication and can be used to demodulate amplitude-modulated signals and/or amplitude-modulated signals with preset correction of amplitude modulation percentage. Proposed method and device feature two-electrode nonlinear component connected in between quadripole and HF-load connected into cross circuit. Previously mentioned quadripole consists of at least three reactive dipoles, their parametres being selected to provide for required modulation percentage.

EFFECT: increased noise-immunity with preset amplitude modulation depth.
