Abstract
A control portion detects the presence or absence of a pulse signal provided from a satellite broadcast receiver through a port PO to output a control signal PDOUT. In accordance with control signal PDOUT, a power supply circuit stops a supply of one of a power supply potential BIASfed to LNAA and a power supply potential BIASfed to LNAB. Therefore, the power consumption in an LNB designed for multi-satellite can be reduced and even a satellite broadcast receiver having a small current-supply capability can be connected. In this way, a low noise block down converter for multi-satellite with lower power consumption can be provided.
