2 BROADBAND CATALOGUE DVB-T Gap Fillers and Digital & Analogue Microrepeaters INTRODUCTI The RA family of DVB-T Gap-Fillers and Digital&Analogue Microrepeaters from IKUSI has been created for: a) providing coverage to shadow zones for DTT (digital terrestrial television), b) retransmitting VHF or UHF analogue channels on UHF channels, c) retransmitting, as COFDM channels, QPSK(FTA) channels from digital satellite reception, and d) broadcasting, on UHF analogue channels, TV programmes issued from FTA digital satellite reception or video/audio sources. The family includes all the elements that are characteristic of this type of stations, its modular design making easy the construction of stations adapted perfectly to the number of existing channels and to the range and coverage desired. COMPENTS The input channelised ways are constituted by the well-known ClassA headend modules: TPC processors, MTI transmodulators, SRF receivers, MCP modulators. The output amplification is configurated from two modules, one driver (LRA) and one power amplifier (HRA), both having ClassA format. An economical variant of the latter is the HPA-5 ClassA headend amplifier, which provides half RF power and does not feature AGC. Gap-fillers and QPSK(FTA)-COFDM microrepeaters perform broadband amplification of the processed input signals, so they include a unique LRA and, normally, a unique HRA. For coverage increasing purpose, they can include two HRAs, which are connected either to two transmission antennas or to a single one using an auxiliary in-phase combiner. The analogue microrepeaters perform separate amplification, so they include as many LRA+HRA pairs as there are input channels; a low-loss multiplexer (XRA) combines the output TV channels and connect them to the transmission antenna. The family is completed with a radomized, UHF panel antenna (PRA).
