Analogue signal repeater system, (1) where frequency converting repeaters (6- 9, 10-13)' of super-heterodyne or super~regenerative type realised with any of discrete semiconductors, MMIC semiconductors, ASIC semiconductors are applied to optimize signal dynamics by avoiding echo between repeaters (6-9, 10-13) and where each information channel (15, 16) in the system only needs two frequency bands, where each second repeater (7, 9, 12, 10) of the signal cascade (2, 14) repeating the signals within the same frequency band to increase isolation against interference between repeaters and against reflections and signal echo.

Dans ce système (1) répéteur de signaux analogiques, on applique des répéteurs (6-9, 10-13) convertisseurs de fréquence de type super-hétérodyne ou super-régénérateur constitués de semi-conducteurs discrets, de semi-conducteurs MMIC ou de semi-conducteurs ASIC afin d'optimiser la dynamique des signaux en évitant des échos entre les répéteurs (6-9, 10-13). Chaque canal d'information (15, 16) dans le système nécessite seulement deux bandes de fréquence, chaque deuxième répéteur (7, 9, 12, 10) de la cascade de signaux (2, 14) répétant les signaux dans la même bande de fréquence afin d'augmenter l'isolation contre les interférences entre répéteurs et contre des réflexions et des échos des signaux.
