We describe the design, fabrication and bench-study of a mm-wave cavity employed as a relativistic klystron output structure. The OFE copper cavity was prepared by electro-discharge machining and diffusion bonding, cleaned, and tuned to 91.4 GHz. Measured cavity characteristics are presented and compared with theory, including quality factor, Q, coupling parameter {beta}, scattering matrix S{sub 11}, and axial electric field profile E{sub z}. This work provides the basis for understanding of the cavity as a transfer structure
