Flexible 4 Channel Analog In/Out
Single-Chip Adaptable Platform
200 Gb/s Digital I/O
Multi-channel Direct RF Sampling on a Single Chip
With flexibility to serve applications like 5G, RADAR, test & measurement and satellite communications, BittWare’s new RFX-8440 features the latest third-generation RFSoC UltraScale+ Zynq device from Xilinx.
4 Channel Analog In/Out
Tapping three decades of experience in designing sensor processing cards, BittWare’s analog front-end features variable gain in/out down to -40 dBm (input) and optimized for L Band. Other analog configurations available.
Do More in the Digital Domain
At the center of the new RFX-8440 is the latest generation single-chip RFSoC from Xilinx, the Zynq ZU43. This device is designed to bring together multi-channel data conversion and processing on a single chip.
“Now with complete coverage of sub-6GHz spectrum bands available as a readily-deployable PCIe card from BittWare, customers are able to gain a competitive advantage by accelerating the design and development of their next-gen wireless systems today.”David BrubakerSenior product line manager, Wired and Wireless Group, Xilinx
RFX-8440 PCIe card, show with optional dual QSFP28s. Card is designed to work in a host system or standalone.
Analogue Front End Options
The default configuration for the analog front end targets L-band (1GHz to 2GHz). We also offer other configurations that remove several stages to provide a direct connection with baluns supporting up to 4 GHz. Contact us for other options.
Option 1: L Band
This option includes several signal conditioning components including variable gain.
Option 1: L Band Frequency Response
Option 2: Direct 3GHz Balun
This option eliminates amplifier distortion and the L-band signal conditioning.
Option 3: Direct 4GHz Balun
Similar to Option 2, but with an extended input range to 4 GHz.

Powered by Third-Generation Xilinx Zynq UltraScale+ RFSoC
At the heart of RFX-8440/RFX-8441 is the Zynq ZU43 RFSoC: a powerful single-chip adaptable radio platform providing up to 6 GHz of direct RF sampling. With a multi-element processing system: FPGA, real-time dual-core ARM and a second quad-core ARM, this RFSoC has what it takes to acquire, process and act on RF signals.
- Industry’s only adaptable single-chip radio platform
- Move RF design to the digital domain
- Programmable logic for diverse requirements and emerging standards
- Lower power by eliminating JESD204 interfaces
- Reduce PCB area vs. discrete solutions
- Future-proof comprehensive solution
- Full sub-6GHz support with extended millimeter wave interfacing and multi-band support
