Abstract The working principle, structural characteristics, performance verification, and uncertainty evaluation of the 170~260GHz portable cold noise standard source newly developed by the 13th Research Institute of China Electronics Technology Group Corporation is introduced. The device adopts a matched wedge load immersed in a rectangular waveguide cooled by liquid nitrogen, and transmits noise power directly to the output waveguide port at room temperature through the waveguide transmission line. By simulating the design and reliable installation of wedge loads, low reflection output of the noise source is achieved. A vacuum pumping scheme is adopted to make the noise source portable, and accurate calibration of the noise source is achieved based on precise temperature control.Through analysis and experiments, it is shown that the output standing wave ratio of the standard source is less than 1.2, the output noise temperature is less than 140K, the uncertainty of output noise temperature is less than 7K (k=2).

Key words： electronic metrology cold noise standard source noise temperature THz technology;wedge load uncertainty
