RF Explorer Upconverter


RF Explorer Upconverter is a high performance RF frequency mixer to enable input frequency ranges from 100KHz to 250MHz in RF Explorer Spectrum Analyzer and other devices such as SDR and wideband radios.

RF Explorer Upconverter is a multi-purpose device:

  • Includes an Upconverter Mixer to enable frequencies 100Khz - 250MHz in your RF Explorer Spectrum Analyzer or other devices such as RTL-SDR and converts into 530.1-780MHz
  • Internal selectable Low Noise Amplifier of 25dB gain nominal, to increase sensitivity of receivers, Spectrum Analyzers, Oscilloscopes and Near Field antennas in frequencies 100KHz - 4GHz
  • Internal selectable Attenuator 30dB nominal to enable large signal measurement

For more details and usage instructions please check RF Explorer Upconverter datasheet.
