CA 2401999

In a transponder (19) for amplification of a received signal (60) into an antenna (1), to a signal (61) for retransmission, and where the retransmitted signal (61) possibly may have information superimposed, a quenched oscillator (5) is incorporated as amplifying element. The oscillator (5) is preferably of superregenerative type and exhibits negative resistance (30) for the received signal (60). Transponders according to the present invention may be introduced as system elements in a wireless or wire based network to work as intelligent or unintelligent connections in the network. The transponders can also be used in positioning systems.

La présente invention concerne un transpondeur (19) venant amplifier un signal reçu (60) par une antenne (1) de façon à retransmettre un signal (61). En l'occurrence, une information peut venir se superposer au signal retransmis (61). On utilise à cet effet un oscillateur bloqué (5) que l'on intègre comme élément amplificateur. Cet oscillateur (5), qui est de préférence à surrégénération, présente une résistance négative (30) s'opposant au signal reçu (60). Les transpondeurs selon la présente invention conviennent comme éléments s'intégrant à des systèmes dans un réseau hertzien ou filaire pour établir des connexions éventuellement intelligentes dans le réseau. Ces transpondeurs conviennent également à l'intégration dans des systèmes de positionnement.
