Mix, Amplify, and Digitize All in One
Integrated into a single card you can have up/down mixing (up to 35 GHz), amplifiers and filters for first/second/third Nyquist, and the powerful AMD RFSoC direct RF chip
With RFX, You've got Options
At the heart of RFX products is the revolutionary AMD RFSoC chip, giving you a range of advantages over discreet systems. However, BittWare has leveraged our analog and digital design heritage to bring you more than expected from a typical RF card:
- Direct sampling between 50 MHz and 6 GHz
- Built-in amplifier/filter options to target first, second, or third Nyquist zones on a per channel basis
- Built-in down/up convert up to 35 GHz
- Wideband options to bypass the filtering/amplifiers and mixer per channel
- Up to 400 Gb/s digital I/O with options for PCIe- or QSFP-focused architectures
- Modular build options for our WaveBox RF servers
- Standalone (with QSFP I/O) or as PCIe card
Powered by 3rd Gen AMD Zynq UltraScale+ RFSoC
RFX cards and modules are built around the powerful AMD RFSoC devices. We bring analog signals in, but it’s the direct RF chip approach that packs so much analog and digital functionality that many racks of previous equipment are no longer necessary!
- Lower power by eliminating JESD204 interfaces
- Smaller physical space
- Programmable (FPGA) logic for diverse requirements and emerging standards
- Built-in ARM processing lets you do more in a standalone deployment
Designed for WaveBox
The RFX 881 and RFX 771 are designed as standalone cards or as PCIe cards in servers. We recommend the WaveBox family of enclosures and servers for the optimum mix of features and the advantage of purchasing an integrated system. Learn more on the WaveBox product page.
Where RFX Fits
At the heart of RFX cards and modules is the AMD RFSoC chip. It combines many of the traditionally discreet RF analog and digital components into a compact, configurable device. Applications including Satcom and test/measurement can benefit from these revolutionary devices.
But with RFX we’ve gone further–bringing to the PCIe form factor optional mixers, amplifiers, and filters. The RFX is configurable too, with up to four inputs/outputs and first/second/third Nyquist filters. Mixer options up to 35 GHz give you up/down conversion all in a single card or module.
Analog Mixing, Amplification, and Filtering Options
On-Card ADCs, DACs, and Mixer
These cards allow you to choose your preference of ADC/DAC channels, with up to eight total in any combination (contact us for pricing and configuration details).
We also have an optional on-card up/down mixer supporting conversions up to 35 GHz. An output option for additional amplification is also available. See the diagrams for details:
