Abstract
A significant amount of noise temperature can potentially be generated by currently unknown dissipative losses in the beam-waveguide (BWG) shroud. The amount of noise-temperature contribution from this source is currently being investigated. In conjunction with this study, electrical conductivity measurements were made on samples of the DSS-13 BWG shroud material at 8.420 GHz. The effective conductivities of unpainted and painted samples of the BWG shroud have been measured to be 0.01 x 10° and 0.0036 x 10° mhos/m, respectively. This value may be compared with 5.66 x 10° mhos/m for high-conductivity copper.
