With the new R&S NRP150T thermal power sensor, Rohde & Schwarz expands the frequency range of its R&S NRPxT series to 150GHz. The R&S NRP150T is the first RF power sensor to cover all the automotive radar frequency bands, including a new higher frequency band. Here, the ADAS/AD community is working with standardisation authorities to define new frequencies up to 148.5GHz for advanced radar sensors. Beyond automotive applications, the sensor supports power measurements in diverse fields such as satellite communication, inter-satellite links, and radio astronomy, facilitating exploration of higher frequency ranges.
Fast measurement speed and wide frequency range enhance efficiency
The R&S NRP150T thermal power sensor achieves up to 500 measurements per second. Combined with its wide frequency range, this allows for single-sweep measurements across the entire spectrum, accelerating the validation and calibration of vector network analysers and other RF instruments. The sensor is compatible with any application using the next generation 0.80 mm RF connectors for frequencies up to 150 GHz, supporting device development and component manufacturing.
Technical excellence combined with ease of use
The R&S NRP150T thermal power sensor offers a broad dynamic range of -35 to +20dBm and provides long-term stability. It compensates for environmental temperature fluctuations within its 0 to +50°C operating range and exhibits excellent drift performance, remaining resilient to external temperature changes and out-of-band signals. With a maximum voltage standing wave ratio (VSWR) of 1.7, the sensor ensures great matching and efficient power transmission. It is easy to use thanks to USB connectivity, compatible with standard PCs and Android mobile devices using a free remote control app, or through the R&S NRX base unit from Rohde & Schwarz.
NMI traceability
Like all power sensors of the R&S NRPxT series, the new R&S NRP150T sensor also offers traceability to national metrology institutes (NMI), which is a prerequisite for commercial and industrial utilisation of a frequency band. The Physikalisch-Technische-Bundesanstalt (PTB) and other European NMIs collaborated with Rohde & Schwarz were first to establish NMI traceability for D-Band ranging from 110 to 170GHz, using R&S technology. This includes the frequencies up to 150GHz utilized by R&S NRP150T power sensors.
