微波各向异性探测器（MAP）卫星于2001年6月30日发射，它将在跨越20 - 106吉赫兹的五个频段上绘制宇宙微波背景辐射的全天图。MAP包含20个差分辐射计，这些辐射计采用带有被动冷却输入级的高电子迁移率晶体管（HEMT）放大器构建。本文介绍了用于评估和最小化系统误差的设计和测试技术，以及所有五个频段辐射计发射前的性能。
The Microwave Anisotropy Probe (MAP) satellite, launched 2001 June 30, will produce full sky maps of the cosmic microwave background radiation in five frequency bands spanning 20-106 GHz. MAP contains 20 differential radiometers built with High Electron Mobility Transistor (HEMT) amplifiers with passively cooled input stages. The design and test techniques used to evaluate and minimize systematic errors and the prelaunch performance of the radiometers for all five bands are presented.
