Transponder, including transponder system
First Claim
1. A repeater or transponder of super regenerative, analogue type with any of very large dynamic range and very wide bandwidth and band-pass filter characteristic, where the repeater or transponder is capable of receiving external or internal synchronization of its internal quenching system, and where selectivity requirements are adapted to any of information bandwidth and quench frequency, wherein at least two gain blocks, each consisting of a quenched oscillator or quenched amplifier, are interconnected in cascaded or parallel fashion to work as one amplifier, using the external or internal quench synchronization, and said repeater or transponder being adapted to conform with selectivity requirements.

Abstract
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.
