Using the principle of subordination, in the present paper we obtain the sharp subordination and superordination-preserving properties of some convex combinations associated with a linear operator in the open unit disk. The sandwich-type theorem on the space of meromophic functions for these operators is also given, together with a few interesting special cases obtained for an appropriate choices of the parameters and the corresponding functions.
