Pico Macom’s TruSpec TSMS2150 series of professional-grade satellite multiswitches are used in applications that require satellite IF distribution from 950-2150 MHz, including residential and MDU installations requiring high return loss ports. The advanced circuit design incorporates a pin diode matrix to route any of the inputs to any of the outputs by utilizing the 13-14V Right-Circular/Vertical or 17-18V Left-Circular/Horizontal switching control supplied by the satellite receivers, thus eliminating digital artifacts that result from mechanical relay switching. To compensate for insertion loss, both versions use separate built-in amplifiers for satellite and VHF/UHF signals. The TSMS-2150 series multiswitches, used with the external power supply, will supply power to the LNB’s reducing heat build up within the multiswitch and prolong the life of the unit. The TSMS-2150-4A 3×4 satellite multiswitch routes input signals from a single satellite with 2 LNB inputs (950-2150MHz) and an off-air TV antenna input (40-806 MHz) to 4 receiver outputs by means of receiver generated voltage 13-14/17-18VDC. The TSMS-2150-5/4 5×4 satellite multiswitch routes input signals from multiple satellites with 4 LNB inputs (950-2150MHz) and an off-air TV antenna input (40-806 MHz) to 4 receiver outputs by means of receiver generated voltage 13-14/17-18VDC and 22KHz 600mV square-wave tone. The TSMS-2150-5/4 multiswitch can also be used in single satellite applications for upgrade to future HDTV expansion.
