RFX 880 + 771
Direct RF Cards and Modules
Analog: 5 GSPS 14-bit ADCs, 9.7 GSPS 14-bit DACs
Digital: Up to 400 Gb/s I/O
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 880 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
RFX 880: 4x ADCs + 4x DACs
Choose from on-card filtering and amplification targeting first, second, or third (partial) Nyquist. Or choose “wideband” and bring your own external filtering. Here’s the input ADC:
There are four of these ADC channels, each factory configurable (talk to us for pricing and availability).
Four DACs provide 30 to 6 GHz with low-pass filtering. See the datasheet for more details and the transmit side diagram.
RFX 771: Configure Up to 8x Total ADCs or DACs
Choose from on-card filtering and amplification targeting first, second, or third (partial) Nyquist. Or choose “wideband” and bring your own external filtering. Here’s the input ADC:
Depending on the RFSoC chip, the RFX 771 has either fixed 4x ADCs and 4x DACs or a configurable mix of ADCs and DACs up to a total of eight.
These analog channels are each factory configurable (talk to us for pricing and availability).
For the transmit side, see the datasheet for details.
35 GHz Mixer Option
For RFX 880 and RFX 771 cards, a new 35 GHz Up/Down Conversion option gives you even more capabilities right on the card/module.
The available channels and configuration details will vary. Contact us about getting more details and discuss your specific frequency plan.
Here is the input side diagram (see the datasheet for output and more details):
