Abstract

Die Erfindung betrifft eine LNB-Empfangseinrichtung zum Empfangen und Umwandeln von DBS-Signalen eines Satelliten, aufweisend:
einen Antennenblock (21) mit Empfangsproben (30, 31) zum Empfangen orthogonaler DBS-Signale;
einen ersten ZF-Umsetzerblock (22) zur Aufnahme der HF-Signale des Antennenblocks (21), mit vier Mischern (MIX1, MIX2, MIX3, MIX4) für eine erste Frequenzumsetzung und Unterteilung in erste ZF-Signale von vier Bändern, und
eine ZF-Matrix (23) zur Aufnahme der ersten ZF-Signale und Ausgabe an mehrere Ausgänge.The invention relates to an LNB receiving device for receiving and converting DBS signals of a satellite, comprising:
an antenna block (21) having receive samples (30, 31) for receiving orthogonal DBS signals;
a first IF converter block (22) for receiving the RF signals of the antenna block (21), with four mixers (MIX1, MIX2, MIX3, MIX4) for a first frequency conversion and dividing into first IF signals of four bands, and
an IF matrix (23) for receiving the first IF signals and output to multiple outputs.

Erfindungsgemäß ist vorgesehen, dass
an die ZF-Matrix (23) ein zweiter ZF-Umsetzerblock (24) angeschlossen ist, der einstellbare Frequenz- Konverter, vorzugsweise VCOs (40, 41, 42, 43) aufweist, die den ausgewählten Ausgang der ZF-Matrix (23) jeweils auf vorgegebene, feste, von einander verschiedene ZF-Frequenzbänder legen,
ein Kopplerblock (25) diese zweiten ZF-Signale aufnimmt, zu einem dritten ZF-Signal superponiert und auf einen Ausgangsanschluss (54) für kaskadierte Satellitenempfänger ausgibt, über den Umschaltsignale von einer Steuereinrichtung (26) aufgenommen werden, die Steuersignale an die FrequenzKonverter zur Steuerung der ZF-Matrix (23) ausgibt. Die ganze Elektronik ist im LNB untergebracht, es sind keine zusätzlichen Baugruppen erforderlich.

Figure imgaf001
According to the invention, it is provided that
to the IF matrix (23) a second IF converter block (24) is connected, the adjustable frequency converter, preferably VCOs (40, 41, 42, 43) having the selected output of the IF matrix (23) respectively place on predetermined, fixed, mutually different IF frequency bands,
a coupler block (25) captures said second IF signals, superposes them to a third IF signal and outputs them to a cascaded satellite receiver output port (54) via which switching signals are received from a controller (26) which supplies control signals to the frequency converters for control the IF matrix (23) outputs. All electronics are housed in the LNB, no additional assemblies are required.
