The CommAgility CA-D8A4-RF4 is a standlone baseband processing and RF card supporting eNodeB and UE functionality in an LTE-A network.
The card includes four RF channels, tuneable in pairs over a very wide frequency range to cover LTE and unlicensed frequency bands, and with RF bandwidth up to 100MHz to support carrier aggregation and 5G applications. The RF channels include low latency control features to support UE and eNodeB operation. Discrete ADCs and DACs are used to ensure high RF quality. Optional RF front end cards then provide amplification and filtering to support specific bands in over-the-air applications.
The module’s main processor is the TCI6638K2K, part of TI’s Keystone II generation of DSP/ARM SoCs. This SoC provides Layer 1-3 baseband processing, with a Gigabit Ethernet interface to the network. The EPC functionality can also be integrated into the SoC if required, giving a fully stand-alone network. A Kintex FPGA then provides the RF control, digital up/down conversion and processing, interfacing over CPRI to the on board baseband processing or the external SFP+ interfaces.
For eNodeB, the card is supported by CommAgility’s SmallCellPHY-TI and SmallCell STACK LTE Release 10 software. For UE, the card is supported by CommAgility’s MobilePHY-TI and MobileSTACK LTE Release 9 software.
