DBS is a service that allows households to receive television programming directly from a satellite transponder. The LNB is located on the satellite dish antenna and amplifies/downconverts to a 0.7-2.15 GHz IF. The switch matrix is responsible for connecting four of the satellite signals to two indoor set-top controllers, selectable by the viewer’s channel choice. The switch is packaged in a lead (Pb)-free and RoHS-compliant, QFN 4 x 4 mm plastic package. The datasheet is located at:, and samples are available. Pricing depends on quantities.
