Radio Frequency (RF) Front-end Mezzanine

The NAT-FMC-SDR4 is a radio frequency (RF) front-end FMC module that provides eight front panel ports for connection to antennas in wireless networks (4x Rx, 4x Tx). The ADRV9009 RF transceivers provide the transmit/receive functionality, with 200 MHz instantaneous bandwidth per channel. It provides a platform for wireless applications, such as mobile cellular systems with massive MIMO or radio beamforming, which require a large number of phase-coherent antennas.


Two modules may be stacked to provide 8 Rx and 8 Tx channels. When combined with a processing carrier AMC, such as the NAMC-ZYNQ-FMC, the combination of large bandwidth RF-transceivers and a powerful FPGA allows you to create 5G radio units with on-board PHY layer processing or NB-IoT/LTE full-network single-board solutions with base station and core network processing.

Applications include:

  • 4G/5G base station
  • 5G radio unit (RU) with PHY processing
  • Cellular prototyping
  • Phased arrays
  • Radio direction finding and tracking
  • Frequency scanner and signal intelligence
  • Radio astronomy
  • Advanced wireless research
  • Prototyping
  NAT-FMC-SDR8 stack


N.A.T. offers this combination as an orderable product, the NAT-AMC-ZYNQUP-SDR (suffix 4 or 8, depending on the number of stacked FMC modules).

Mounting one or two NAT-FMC-SDR4 RF transceiver FMC module(s) to the NAT-AMC-ZYNQUP-FMC creates the NAT-AMC-ZYNQUP-SDR4 (or 8), which combines high performance FPGA processing with RF front-end antenna connections.

The nature of the mezzannine connectors means that, for an 8-channel module, the variants to mount on the FPGA carrier board are NAT-FMCSDR4-M and NAT-FMC-SDR4-T.
