Transponder, including transponder system
First Claim
1. An analogue repeater and transponder system for any of wireless, wire and waveguide infrastructure based digital networks for at least one transmission medium, comprising:
- at least one of at least one repeater and at least one transponder and where each repeater/transponder has at least one port for connection via signal coupler arrangements to the transmission medium for signal reception and transmission, where each of the repeaters and transponders is of analogue type with positive and large signal gain applicable to wide bandwidth uses and implemented using any of solid state components and solid state integrated circuitry, and where selectivity requirements are adapted to any of information bandwidth and quench frequency or ideal interference isolation between system medium and air free space, wherein the repeaters and transponders are of regenerative type having at least one superregenerative circuit equipped with selectivity arrangements for both input and output signals, wherein the repeaters and transponders are capable of selecting frequency bands generated by the superregenerative circuit, by which bandpass-analogous characteristics of the repeaters and transponders are 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.
