Skyworks Solutions introduces silicon CMOS switch matrix for LNB with tone/voltage decoder. A 4 × 2 switch matrix combining a digital decoder with the RF switching network and tone/voltage detect designed for European and Asian market applications including Direct Broadcast Satellite (DBS) Low Noise Block (LNB) the SKY13292-365LF. 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/down converts to a 0.7 to 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.
