All Satellite Modem Datasheets
We offer two industry-leading brands – Comtech EF Data and Radyne – and the widest range of bandwidth-efficient Satellite Modems in the industry. Our award-winning Modems support satellite-based mobile backhaul, enable broadcast transmissions, power mission-critical military communications, and facilitate connectivity to remote offices. We offer indoor, outdoor / ruggedized and card-based models.
Our Satellite Modems enable deployment in remote and hub environments; we offer L-Band, 70/140 MHz and combination L-Band & 70/140 MHz systems. We offer data rate ranges from 2.4 kbps to 238 Mbps, and provide the options/configurations you need for operation with single or multiple transponders, Low Noise Block Converters and Block Up Converters. Our product line includes open and closed network Satellite Modems, and support for a variety of M&C methods. A wide range of data interfaces are available to support low- and high-speed data transmission.
Our Satellite Modems support traditional and advanced methods of forward error correction to improve performance of error-prone channels. Examples of our FECs are VersaFEC®, DVB-S2, Low Density Parity Check Coding and 2nd Generation Turbo Product Coding. More Info »
Our modulators and demodulators support a range of modulation techniques, including BPSK, QPSK, OQPSK, 8PSK, 16APSK, 32APSK, 8-QAM, 16-QAM and 64-QAM. The combination of advanced FEC and higher order modulation provides increased coding gain, resulting in significant bandwidth and power savings.
Our award-winning DoubleTalk Carrier-in-Carrier is based on Ratheon Applied Signal Technology’s patented “Adaptive Cancellation” technology that allows transmit and receive carriers of a duplex link to share the same transponder space. When combined with our advanced FEC and modulation, it delivers unprecedented savings in transponder bandwidth and power utilization. More Info »
This mechanism solves the power control optimization problem in a very general way for CnC links. It provides a unique opportunity for Satellite Modems on both sides of a CnC link to automatically measure and compensate for rain loss while maintaining a fixed PEB on the satellite during all conditions.

Rain fade, inclined orbit satellite operation, antenna pointing errors, noise and interference can all degrade satellite link conditions. When utilizing ACM operation in our Satellite Modems, link margin can be converted into increased throughput of satellite links. More Info »
Satellite Modems with our integrated router/managed switch functionality allow seamless network convergence for data, voice and video traffic. Available options include header compression, payload compression, ultra low overhead streamline encapsulation and Quality of Service (QoS). More Info »
Our MetaCarrier technology is used to embed and detect Carrier ID information on modulated satellite carriers.
