Abstract

Analogue signal repeater system, (1) where frequency converting repeaters (6-9, 10-13) of super-heterodyne or superregenerative 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.

characterised by 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.

4. Analog signal repeater system according to claim 1,

5. Analog signal repeater system where a combination method (70) achieves isolation between input signal and output signal (73-76) for a repeater (70) with antennas (71, 72) as well as avoids reflections back to the repeater (70)

characterized by the application of two frequency bands using two repeaters (82, 83) that repeat within same frequency band (74-76, 73-75) but where two bi-directional, advantageously one-port repeaters (82, 83) contain differing frequency bands for the two signal directions (74-76, 73-75) to achieve isolation against interference between repeaters and against reflections and signal echo and where the isolation is further increased by additionally facilitating the use of separate amplifiers for input and output signals (77-80, 78, 79) as well as opposite antenna polarisation or coupler polarity for the differing signal ports (73-74, 75-76).
