Comtech CDD-564AL Four-Channel L-Band IP Demodulator

Comtech CDD-564AL Four-Channel L-Band IP Demodulator

The Comtech CDD-564AL is a four-channel L-band IP demodulator designed for satellite hub, hub-spoke and mesh networks. Four independently configurable demodulators receive separate L-band carriers and combine the recovered IP traffic onto a single Ethernet interface. Its compact 1RU architecture reduces hub rack space while supporting VersaFEC, TPC and optional Vipersat bandwidth management.

Frequency Range: 950–2250 MHz
Number of Channels: Four independent L-band demodulators
Data Rate: 16 kbps to 10.239 Mbps per demodulator
Maximum Symbol Rate: 3 Msps per demodulator
Demodulation: BPSK, QPSK, OQPSK, 8PSK, 8-QAM and 16-QAM
Traffic Interface: 10/100Base-T Ethernet
RF Inputs: Four Type-N female connectors
Applications: Satellite hubs, hub-spoke networks, mesh connectivity, maritime communications, enterprise networks and satellite news gathering
