摘要

由于使用非冷却混频器接收机的43 GHz 100米射电望远镜具有优异的性能[1]，因此在40-50 GHz范围内构建了冷却混频器接收机。总单边带系统噪声温度为250k。估计混频器噪声温度是160 K使用莫特二极管。给出了技术测量和天文测量样本。

The 40-50 GHz Cooled Mixer Receiver for The 100-Meter Effelsberg Radiotelescope

Due to the excellent performance of the 100 meter radiotelescope at 43 GHz using an uncooled mixer receiver [1], a cooled mixer receiver was constructed for the 40-50 GHz range. The total single-sideband system noise temperature is 250 K. The estimated mixer noise temperature is 160 K using a Mott diode. Technical and sample astronomical measurements are presented.
