RF Power Sensor Offers Gapless DC to 150-GHz Coverage
Boasting a next-generation high-performance, coaxial 0.80-mm RF connector that supports frequencies up to 150 GHz, the R&S NRP150T thermal power sensor from Rohde & Schwarz expands the frequency range of its R&S NRPxT series to 150 GHz. According to the company, sensor provides the widest non-banded frequency range of any commercially available RF power sensor. It streamlines the validation and calibration of RF instruments.
Presented as the first RF power sensor to cover all of the automotive radar frequency bands, including a new higher frequency band, the R&S NRP150T can serve frequencies up to 148.5 GHz for advanced radar sensors. It also handles power measurements in diverse fields such as satellite communication, inter-satellite links, and radio astronomy.
The R&S NRP150T offers a fast measurement speed and wide frequency range to enhance efficiency. It performs up to 500 measurements per second for single-sweep measurements across the entire spectrum, accelerating the validation and calibration of vector network analyzers and other RF instruments.
Features include a dynamic range from –35 to +20 dBm with long-term stability, compensating for environmental temperature fluctuations within its 0 to +50°C operating range, with excellent drift performance. All the while, it remains resilient to external temperature changes and out-of-band signals.
With a maximum voltage standing wave ratio (VSWR) of 1.7, the sensor ensures matching and efficient power transmission. Its USB connectivity is compatible with standard PCs and Android mobile devices, or through the R&S NRX base unit.
Like all of the series, the R&S NRP150T sensor also provides traceability to national metrology institutes, a prerequisite for commercial and industrial use of a frequency band. The Physikalisch-Technische-Bundesanstalt and other European NMIs collaborated with Rohde & Schwarz to establish NMI traceability for D-band ranging from 110 to 170 GHz, using R&S technology, including frequencies up to 150 GHz.
