We report on the results of an EPIC XMM-Newton observation of the faintsource SAXJ1748.2-2808 and the surrounding field. This source was discoveredduring the BeppoSAX Galactic center survey performed in 1997-1998. A spatialanalysis resulted in the detection of 31 sources within the EPIC field of view.SAXJ1748.2-2808 is clearly resolved into 2 sources in EPIC images with thebrighter contributing almost 80% of the 2-10keV flux. Spectral fits to thismain source are consistent with an absorbed power-law with a photon index of1.4+/-0.5 and absorption equivalent to 14E22cm-2 together with an iron line at6.6+/-0.2 keV with an equivalent width of ~780eV. The significantly betterstatistics of the XMM-Newton observation, compared with BeppoSAX,allows toexclude a thermal nature for the X-ray emission. A comparison with otherobservations of SAXJ1748.2-2808 does not reveal any evidence for spectral orintensity long-term variability. Based on these properties we propose that thesource is a low-luminosity high-mass X-ray binary located in the Galacticcenter region.Comment: accepted for publication in A&
