NUT4NT+

Four-Channel Multi-Band GNSS SDR with FPGA

With two NT1065 RF-to-Bits ICs the NUT4NT+ board is suitable for antenna diversity GNSS SDR applications. With Lattice ECP5 FPGA onboard the NUT4NT+ is in same time a low-cost and low-power device. All other features inherited from our legacy NUT4NT and new NUT2NT+ design. Two outstanding features are onboard IMU and 24-bits DAC for fine TCXO frequency control. 

Board specifications:

  • Receiver ICs: two of NT1065

  • USB 3 COntroller: CYUSB3014

  • USB Connector: USB Type-C

  • FPGA: Lattice ECP5, 86 K LUTs + 156 DSP

  • Clock: 10 MHz TCXO, 24-bits DAC controled frequency

  • RF inputs: four, wideband with 3 dB NF

  • ADC resolution: 2 bits

  • ADC frequency: up to 99 MHz

  • Power consumption: 5V @ 0.5A from USB

  • Size: 100 mm x 50 mm x 10 mm

  • GNSS standards: GPS, GLONASS, Galileo, BeiDou, IRNSS, and future standards

  • All GNSS band: L1/L2/L3/L5, G1/G2/G5, B1/B2, E1/E5, and future bands

  • Power injector circuit: for antennas with a DC short
