Name: Adaptive Broadband SDM-2020 Satellite / RF Ground Equipment
Brand: Adaptive Broadband
SKU: SDM-2020

Adaptive Broadband SDM-2020 DVB-compliant satellite modem/demodulator, QPSK/8PSK, for broadcast and data links.

The Adaptive Broadband SDM-2020 is a satellite modulator/demodulator supporting DVB-compliant QPSK and 8PSK modulation, used for digital broadcast and data delivery over satellite. Adaptive Broadband (successor to the Comstream/California Microwave satellite equipment line) built the SDM-2020 as a flexible modem for DVB-S carriers, supporting the forward error correction and framing required for standards-compliant broadcast and IP-over-satellite links. It sits in the earth station RF chain between the baseband/transport stream interface and the upconverter/downconverter, providing configurable modulation, FEC and symbol rate settings to match link budget and bandwidth requirements. Modems of this type were widely deployed by broadcasters, teleports and satellite data network operators through the 2000s for DVB-S distribution and contribution links. Tech-Star (UK-based, shipped worldwide) supplies tested Adaptive Broadband SDM-2020 modems. Contact us to confirm stock and current configuration.
