We consider a class of models in which supersymmetry breaking is communicated dominantly via a U(1){sup '} gauge interaction, which also helps solve the {mu} problem. Such models can emerge naturally in top-down constructions and are a version of split supersymmetry. The spectrum contains heavy sfermions, Higgsinos, exotics, and Z{sup '}{approx}10-100 TeV, light gauginos{approx}100-1000 GeV, a light Higgs boson{approx}140 GeV, and a light singlino. A specific set of U(1){sup '} charges and exotics is analyzed, and we present five benchmark models. The implications for the gluino lifetime, cold dark matter, and the gravitino and neutrino masses are discussed.
