We discuss the phenomenological consequences of soft supersymmetry breaking terms in the KKLT scenario with all the moduli fixed at a de Sitter vacuum which is constructed by adding supersymmetry breaking branes providing the uplifting potential. The structure of low energy soft terms and the possibility of electroweak symmetry breaking are examined in the KKLT models. In addition, we examine the effects of anomalous $U(1)_A$ gauge symmetry on soft terms within the KKLT stabilization of the modulus implementing the Green-Schwarz anomaly cancellation mechanism. It is noted that the mirage mediation of supersymmetry breaking is a natural consequence of the KKLT stabilization of string moduli in which the anomaly mediation typically gives comparable contributions to soft supersymmetry breaking terms with the modulus mediation and the $U(1)_A$ mediation. The mirage mediation leads to a quite distinctive pattern of low energy superparticle spectrum as a consequence of the particular correlation between the anomaly mediation and the RG evolution of soft parameters.
