Rohde & Schwarz launches R&S NRP140TWG(N) thermal power sensor: A new benchmark for F band applications

13/03/2025

Rohde & Schwarz launches R&S NRP140TWG(N) thermal power sensor: A new benchmark for F band applications Rohde & Schwarz presents the new R&S NRP140TWG(N) thermal power sensor, designed to meet the growing demands of applications in the F band utilizing a WR 8 waveguide connector. The NRP140TWG(N) is fully traceable to the National Metrology Institute (NMI) in Germany (PTB) and is temperature compensated, ensuring accurate and reliable measurements. With its plug-and-play capability, users can easily connect via USBTMC or LAN digital connectivity, making it an ideal solution for a wide range of applications.

The new R&S NRP140TWG(N) follows the excellent R&S NRP170TWG power sensor which was the first thermal power sensor to cover the full D band. With the new sensor, Rohde & Schwarz now also offers a dedicated solution for precise power measurements in the F band, using an WR 8 waveguide connector.

Accuracy is vital to complex wideband measurements. Therefore, the sensors are fully calibrated for long-term stability and can compensate for environmental temperature influences within the specified operating range from 0 C to + 50 C. R&S NRP140TWG(N) sensors have a dynamic range of -35 dBm to +20 dBm and up to 500 measurements per second, making them extremely fast with outstanding performance. They are the only NMI-traceable RF power sensors for the F band.

Prepared for new upper-band automotive radar and SatCom applications

As the ADAS/AD community collaborates with standardization authorities to define new frequency bands for automotive radar, the R&S NRP140TWG(N) is ready to facilitate safer radar-based ADAS and autonomous driving technologies. With the increasing exploration of higher frequency bands in satellite communications, the R&S NRP140TWG(N) has already attracted orders from major space companies, underscoring its relevance in this critical industry. Further, the sensor is essential for RF power measurements in any application utilizing WR 8 waveguide connectors, including T&M instrument level verification, amplifier characterization, device development, and regulatory compliance.

Ease of use

All Rohde & Schwarz NRP power sensors are easy to use and stable with excellent connectivity, letting researchers, developers and production engineers focus on more challenging tasks. R&S NRP140TWG(N) sensors provide stable power readouts even at low power levels, have excellent drift performance and are resilient to external temperature changes or out-of-band signals. R&S NRP140TWG(N) are easy to use thanks to USB or LAN connectivity.

NMI traceability

In collaboration with Germany's national metrology institute Physikalisch-Technische-Bundesanstalt (PTB) and other European NMIs Rohde & Schwarz was first to establish NMI traceability up to 170 GHz for the R&S NRP170TWG. Now, the new R&S NRP140TWG(N) sensor offers full NMI traceability in the frequency range from 90 GHz for to 140 GHz. NMI traceability is a prerequisite for commercial and industrial utilization of a frequency band.

The new R&S NRP140TWG(N) thermal power sensors are now available from Rohde & Schwarz. For further information visit: R&S NRPxxT/TN/TWG/TWGN
