Arrangement for separating multi-channel frequency-modulated SHF television or radio programmes

摘要

The invention relates to an arrangement for separating multi-channel frequency-modulated SHF television or radio programmes broadcast via a satellite. The SHF antenna signal is fed in parallel to two downlink mixers which are activated via a 0 DEG /90 DEG power divider. The programme channels are separated by means of a further 0 DEG /90 DEG power divider to whose outputs selection means and PLLs are connected.
