Effective January 1st 2022, ICE Enterprises will increase all product prices by 20%. Market forces, both rising component cost and increasing material lead time, are requiring the first price adjustment in company history. This price increase will allow ICE Enterprises to continue to design and manufacture quality electronic hardware as has been the case for over two decades. ICE Enterprises will honor all current price quotes and accept orders at existing pricing through the end of December 2021.

Digital to RF Convertor 70 MHz – 4 GHz
D2RF Top
D2RF Bottom

This single site module accepts streaming complex signal data and up-translates to a frequency range from 70 MHz - 4 GHz. The control software interface (included with the module) displays amplitude vs. time (Oscilloscope), amplitude vs. frequency (spectrum), and frequency vs. time (falling raster). Parameters for control of the module are also available for custom library interface directly to the module. The bandwidth is software selectable from 1 to 50 MHz. Two ICE-D2RF modules can be mounted on an ICE-PIC card for dual channel applications.

An internal 10 MHz reference can be used by selecting the onboard 10 MHz reference or 10MHz reference can be provided via SMB connector. An external 1 PPS signal, via SMB connector can be used.


Features

  • Easy, clean transmit spectrum from 70 MHz – 4 GHz at -10 dBm

  • Data Inputs:
    Complex data from memory
    Streaming complex data from suitable high-speed storage
  • Digital Output (LVTTL) via Digital I/O port up to 100 Megabits/sec
  • Single-site module for use with ICE-PIC6 or newer DSP cards, also for use with ICEPOD series portable devices

Applications

  • Signal Transmission
  • Input to High Power Amplifier For Transmit
  • RF Spectrum Environment Simulation
  • Communications
  • Instrumentation
