Indoor digital video broadcasting terrestrial repeater for use in building, has amplification paths, signals fed into amplification branches, and output path leading to transmitting antenna and to output to which antenna is connected

摘要

The repeater has two amplification paths (9a, 9b) for two frequency bands, where a circuit with band-pass and band-stop filters is provided in the paths. Two signals in the respective bands are fed into two amplification branches and are separately amplified. The signals are interconnected over a filter and/or summing circuit. An output path leads to a transmitting antenna and to an output to which the antenna is connected.
