Spectrum Signal Processing has introduced its FlexComm SDR-2000, a satellite communications (SATCOM) rapid-prototyping and development platform (SRDP). It is a fully integrated IF-to-Ethernet commercial off-the-shelf (COTS) software-defined radio platform. The platform is designed for the rapid development and deployment of satellite ground stations supporting bidirectional communications with multiple remote terminals. The SDR-2000 follows on the heels of the SDR-3000 MRDP, a military communications (MILCOM) platform introduced in November 2004.

The SDR-2000 SRDP is a PCI/PCI-X-based platform housed in a 2U dual Intel Xeon server that supports Red Hat Enterprise Linux ES. The system has been configured to support multiple, simultaneous carriers inherent in the frequency allocation schemes that characterize many single-channel-per-carrier and multifrequency, time-division, multiple-access-based satellite networks.

The SDR-2000 SRDP supports two receive channels and one transmit channel at the SATCOM industry-standard, intermediate frequencies of 70 MHz and 140 MHz, with IF bandwidths in excess of 72 MHz. The platform integrates a high-performance FPGA-based, wideband IF transceiver with multiple multiprocessing engines on ePMC/XMC-to-PCI PRO-2900 carrier cards.
