Digital IF Processors & Waveform generators

We offer six-channel digital IF receiver modules and DRFM cards that digitize, process, and generate waveforms in real time. Built on FPGA and high-speed ADC/DAC technology, they enable advanced radar and electronic warfare applications.



6 Channel Digital Receiver Module

Product ID NM-EXP-7836
Product Name 6 Channel Digital Receiver Module
Product Description NM-EXP-7836 is a VME64x Six Channel Digital IF Receiver module. It samples and down converts analog IF signals into the digital base band data.The digital base band I/O samples generated from these IF samples are pulse compressed. Down converted I/Q data is sent to the signal processor through 2 channels of 2.5 Gbps speed SFPDP link.The digital waveform generator block of digital receiver unit generates programmable polyphase coded digital pulse coded expander output.
Key Features
  • VME 64x interface card.
  • High-performance 14-bit monolithic ADCs.
  • Waveform generation DAC.
  • DC-coupled dual-channel 16-bit DACs.
  • Six ADCs with three Virtex-4 FPGAs (two ADCs per FPGA).
  • 512 MB Flash for coded waveform reference data.
  • User-programmable algorithms.
  • Temperature monitoring.
  • Two serial FPDP optical links @ 2.5 Gbps each.
  • Supports down-conversion and pulse compression.
  • Rugged construction.

Digital Radio Frequency Memory Card (DRFM)

Product ID NM-AWP-6549
Product Name Digital Radio Frequency Memory Card
Product Description The NM-AWP-6549 is a VPX based standard module, which is used to measure the Amplitude, Phase & other parameters of the RADAR signal in real time using high speed ADC, DAC & FPGA architecture. DRFM digitizes an IF Signal of the intercepted radar waveform, modifies the phase/amplitude of the signal in FPGA, and coherently rebroadcasts the modified signal. DRFM effectively handles instantaneous bandwidth of 400MHz.
Key Features
  • 400 MHz instantaneous bandwidth with attenuation control.
  • Pulse widths: 50 ns to CW.
  • Range delay: 500 ns to 500 ms.
  • Range resolution: 3.33 ns.
  • Four × 2 Gbit DDR-III memory banks.
  • 4 Mbit Flash memory.
  • High-speed PCIe and RIO interfaces.
  • Single-channel high-speed 12-bit ADC.
  • Single-channel high-speed 16-bit DAC.
  • ADC/DAC flatness < ±2 dBm.
  • User-programmable Xilinx Virtex-7 FPGA.
  • Output attenuation control.
  • External trigger input/output.
  • External VCO input option.
