The compact double sources 1518 + 047, CTD 93, and 2050 + 364 have been mapped at 5 GHz using a five-element VLBI array. Comparison with previous maps at 1.6 GHz shows that individual components of each double have nearly identical steep spectral indices, consistent with the models in which both components originate on opposite sides of a central energy source. Individual components often show complex structure, including the head-tail morphology characteristic of luminous, extended double sources. The measured angular sizes and spectrum of each subcomponent are consistent with synchrotron emission in a magnetic field of B value of about 10 to the -4 + or -1 gauss which becomes self-absorbed at the observed turnover frequencies. Ram-pressure confinement of the radio lobes is possible for lobe velocities of v = 10 to the -1.3 + or - 0.7 c.
