We present a new model for the non-thermal emission of microquasars based on an expanding relativistic jet confined by cold plasma. A population of leptons is accelerated up to relativistic energies by shocks in the jet. The model accounts, in a self-consistent way, for the different radiative losses of these particles, including synchrotron radiation, inverse Compton emission from seed photons both external and internal to the jet, and Bremsstrahlung emission in the stellar wind. Photon absorption in the different ambient fields and emission from secondary electron-positron pairs were also considered in the calculations. Within this framework, we present different predictions along the entire electromagnetic spectrum for a variety of models.
