WILDSTAR 3XR2 3U OpenVPX FPGA Processor – WB3XR2
The WILDSTAR 3XR2 FPGA Processor is 100GbE-enabled, SOSA-aligned, and it leverages the processing and A/D & D/A converting power of two Gen 3 Xilinx UltraScale+™ RFSoC FPGAs. Plus, the 3XR2 offers a full-length coax-connected Analog Interface Mezzanine Site. See below for the benefits of this Site.
Need the same SOSA-alignment and 100GbE capability in a 6U VPX form factor? See the WILDSTAR 6XB2 6U OpenVPX Board.

These FPGA boards are SOSA-aligned Plug-In Cards (PIC). They offer an Analog Interface Mezzanine Site that can be populated in one of three ways:
- With a direct RF digitization mezzanine
- With simple analog circuitry (filtering, amplification, etc.)
- With a 3rd party or customer-supplied analog tuner to allow for digitization of higher frequency signals
Combining filtering and tuning with digitizing and processing delivers much lower SWaP-C than separate single-function modules, while maintaining the ability to upgrade either capability separately.
Annapolis’ powerful BSP options include 40/100GbE IP and Linux support.
