  We present two simple designs of matter-wave beam splitters in a trapped
Bose-Einstein Condensate (BEC). In our scheme, identical pairs of atomic
solitons are produced by an adequate control --- in time and/or space --- of
the scattering length. Our analysis is performed by numerical integration of
the Gross-Pitaevskii equation and supported by several analytic estimates. Our
results show that these devices can be implemented in the frame of current BEC
experiments. The system has potential applications for the construction of a
soliton interferometer.
