FIELD: telecommunication equipment.
SUBSTANCE: invention relates to telecommunication equipment, particularly to perspective combined systems of fiber-ether structure, typical representatives of which are intensively developing local distributed systems of class ROF (Radio-Over-Fiber). Module comprises receiving antenna 1, mixer 2, band-pass filter 3, intermediate frequency amplifier 4, total frequency amplifier 5, amplitude detector 6, switch 7, directional coupler 8, first 9 and second 10 lasers, photodiode 11, electronic amplifier 12 and unit 13 recovery of carrier frequency.
EFFECT: technical result consists in improvement of interference immunity of frequency converter by suppression of false signals, interference received on additional channels.
