Microwave radiometer blackbody calibration standard for use at millimeter wavelengths.
We describe a high-temperature reference load designed for calibration of microwave radiometers at frequencies of 80-150 GHz. An effective temperature of 410 K and a power reflection coefficient of less than 5 x 10(-4) have been measured at frequencies between 85 and 95 GHz.
