The Rohde & Schwarz NRP75TWG is a thermal power sensor engineered for high-accuracy measurements across the 50 GHz to 75 GHz band. This precision instrument delivers a 55 dB dynamic range with power handling from -35 dBm to +20 dBm, supported by exceptional linearity and impedance matching at 50 Ω nominal. The sensor achieves measurement noise below 28 nW (typical 20 nW) and zero offset under 28 nW, making it suitable for aerospace, defense, and telecommunications applications where measurement certainty is critical.
