Q8RF
Powerful First-Generation RFSoC SDR/Processor Card
The Xiphos Q8RF is based upon the well-regarded Zynq UltraScale+ RFSoCs (RF System-on-Chip) devices. These are highly integrated system-on-chip devices from AMD Xilinx that combine high-speed RF-class ADCs and DACs, programmable FPGA logic, and embedded ARM processors on a single chip. This architecture enables direct RF sampling and real-time digital signal processing without the need for external data converters or complex analog front ends. By tightly coupling processing and conversion resources, RFSoCs significantly reduce system size, weight, power, and latency - making them ideal for advanced RF applications that demand high channel density, wide bandwidth, and low-latency signal chain control.
Xiphos has combined these RFSoC devices with its fault-tolerant space architecture that has been developed over more than two decades to ensure trouble-free operation in-orbit.
Also check out the newer Q8RFG3 which is based on the third generation of Xilinx RFSoC devices, adding upgrades to the digitization portion of the architecture, the RF input bandwidth and the ability to synchronize multiple Q8RFG3s together for applications such as digital beam forming.
