  Some phantom cosmological models without big rip singularity have been
constructed in a simple extended theory of gravity. In the geometrical part of
the action, a minimally coupled linear function of the Ricci Scalar and the
trace of the energy momentum tensor have been considered in place of the Ricci
scalar. Four Little Rip and Pseudo Rip models have been investigated where the
equation of state parameter evolves asymptotically and sufficiently rapidly to
$-1$. The effect of the coupling constant of the extended gravity theory on the
dynamics has been discussed. Possible wormhole solutions for the phantom models
are obtained. The possibility of Big Trip in wormholes are discussed for the
models.
