COM-1824 Channel simulator

The COM-1824 is a real-time digital channel simulator featuring multi-path fading, white Gaussian noise, frequency translation and long propagation delay (satellite link)

  • Multi-path: Rician (some line of sight), Rayleigh (no line of sight), Lognormal shadowing
  • Precise additive White Gaussian Noise
  • Long propagation delay, up to 256 MSamples for satellite link simulation
  • Maximum sampling rate 120 MSamples/s, complex, 16-bit precision. Support for complex baseband input and IF undersampling
  • Multi-path: 16 complex baseband paths (one direct, 15 scattered or reflected paths)

COM-1827SOFT CPM modulator


  • The COM-1827SOFT CPM MOD is a continuous Phase Modulator, VHDL source code & IP core
  • VHDL source code / IP core implementing several continuous phase modulations: FSK, MSK, GFSK, GMSK, PCM/FM, SOQPSK-MIL, SOQPSK-TG
  • Flexible run-time configuration with programmable data rates (up to fclk/4)
  • Pure VHDL source code for easy port to a variety of FPGAs

COM-4009 Digital to [400MHz-4.4GHz] broadband quadrature RF modulator

The COM-4009 takes 12-bit I/Q LVDS baseband input samples and translates the center frequency anywhere in the range 400 MHz to 4.4 GHz.

  • RF synthesizer step size 5KHz or less
  • Low phase noise (-82 dBc @ 1 KHz offset, 3 GHz)
  • Agile frequency synthesizer: 200us retuning. 8 stored frequencies
  • Measures output power and temperature
  • Internal VCTCXO or external higher stability 10 MHz frequency reference
  • Connects directly to COM-1800 FPGA development platform
