Economically Extend Your Frequency & Bandwidth Performance to mmWave Bands

RF frequency converters are one of the most economical and cost-effective methods for increasing the frequency performance of RF signal analysis systems. In the new world of 5G networks, a RF frequency converter can reduce time to market and costs for mobile operators, system integrators, telecom carriers and baseband researchers.

thinkRF RF frequency converters cover up to 44 GHz with 800 MHz of analog bandwidth for open environment (spectrum monitoring) and controlled environment (lab / production testing) applications. Extend the life of your existing field, lab, and manufacturing test equipment, and reduce time to market and costs when measuring 5G mmWave signals.

thinkRF RF Downconverters/Tuners Use Cases

RF Spectrum Monitoring

  • RF down-conversion for 24 – 40 GHz signals, to extend range of existing equipment for 5G analysis
  • Retain existing field/lab, and manufacturing test equipment
  • Reduce time to market and costs for mmWave analysis
  • Single IF output – easy integration with spectrum analyzers or receivers
  • Compact form factor – maintains portability and versatility in any deployment scenario
  • Best price-performance ratio – enables translation of 5G mmWave in 24 – 40 GHz
  • Pre-select filtering – eliminates out-of-band signals, enables spurious mitigation, and reduces interference
  • Wideband – up to 500 MHz of real-time bandwidth enables multiple units in parallel for wideband signal analysis
  • Synchronization capability – includes 10 MHz i/o clock reference to support clock synchronization with external modules, which is, particularly useful for wideband signal monitoring/capture
