About

The Xiphos Q8RF family is based upon the well-regarded Zynq UltraScale+ RFSoCs (RF System-on-Chip) devices from AMD Xilinx, which 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 external data converters or complex analog front ends, significantly reducing system size, weight, power, and latency for advanced RF applications requiring high channel density, wide bandwidth, and low-latency signal chain control. Xiphos has combined these RFSoC devices with its fault-tolerant space architecture, developed over more than two decades, to ensure trouble-free in-orbit operation. The new Q8RFG3 is based on the third generation of Xilinx RFSoC devices, adding upgrades to the digitization portion of the architecture, increased RF input bandwidth, and the ability to synchronize multiple Q8RFs together for applications such as digital beam forming.
