The Rohde & Schwarz NRP18T is a thermal power sensor for precise average and CW power measurements from DC to 18 GHz. Built for production, R&D, and calibration laboratories, it delivers measurement uncertainty below 1.8% at 1 mW with excellent impedance matching and modulation tolerance. The sensor accepts peak power to 10 W (1 µs maximum) and continuous average power to 300 mW, making it suitable for both low-level and moderate-power applications.
