Rohde & Schwarz has developed what it says is the world’s first RF power sensor featuring a 0.80mm RF connector that enables continuous coverage from DC to 150GHz. The new R&S NRP150T thermal power sensor offers the widest non-banded frequency range of any commercially available RF power sensor, opening up new possibilities in high-frequency power measurement, including emerging automotive radar bands. It also simplifies the validation and calibration of RF instruments.
The R&S NRP150T extends the upper frequency limit of the company’s NRPxT series to 150GHz and is the first RF power sensor capable of covering all automotive radar frequency bands, including new higher-frequency ranges.
The ADAS/AD community is working with standardization authorities in this domain to define new frequencies up to 148.5GHz for advanced radar sensors.
The R&S NRP150T thermal power sensor delivers up to 500 measurements per second, and its wide frequency range enables single-sweep measurements across the full spectrum. This greatly speeds up the validation and calibration of Vector network analyzers and other RF instruments. The sensor is also compatible with applications using next-generation 0.80mm RF connectors up to 150GHz, supporting both device development and component manufacturing.
The sensor offers a broad dynamic range of -35dBm to +20dBm and provides long-term stability. It compensates for environmental temperature fluctuations within its 0°C to +50°C operating range and exhibits excellent drift performance, according to Rohde & Schwarz, 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 and 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.
