This chapter describes the origin and characteristics of the Cosmic Microwave Background radiation, the source of most of the millimeter wave photons in the universe. The measurements from the COBE satellite of the temperature and morphology of the CMB on large angular scales are summarized. The theoretical origin of anisotropies in the CMB and the predicted power spectrum of fluctuations is presented. These power spectra are shown to have a strong dependence on the cosmological parameters Ω0, Ωb, H0, ΩΛ, n. Current millimeter-wave experiments are approaching the sensitivity levels necessary to accurately determine some of these parameters.
