We present 2D projections of 3D simulations of the quiet-sun radio-emission, at different frequencies on the centimeter-submillimeter wavelength range (specifically at 1.4, 3.9, 17, 34, 43, 110, 212 and 250 GHz). We have built a 3D, spherically symmetric, solar model and solved the classical equation of radiative transfer using quiet-sun temperature and electronic density models. We compare our results with Nobeyama Radio Heliograph observations at 17 GHz. The 3.9 and 43 GHz images will be useful to calibrate the observations of the new 5 meter millimeter telescope (RT5) which is going to be installed at "Sierra Negra" Volcano, in the state of Puebla, Mexico, at an altitude of 4,600 m. over the sea level. This project is a collaboration between Instituto Nacional de Astrofisica Optica y Electronica (INAOE) and Universidad Nacional Autonoma de Mexico (UNAM).
