1/ At 20°C waveguide temperature.
2/ These values were determined by calculating the non-pressurized air dielectric breakdown strength
produced by considering the E field within the waveguide. This determination was based on the peak
value of a continuous wave (CW) signal. For further information see M. Gilden and L. Gould, "Handbook
on High Power Capabilities of Waveguide Systems," June 1963, Navy Contract Nobsr-85190, Index No.
SR0080302, ST 9604.
3/ These values were determined by calculation of the rate of heat loss to the ambient, considering a non-
pressurized air dielectric waveguide in air using no artificial heat sink. A maximum waveguide
temperature of 71°C, 1:1 VSWR, and an ambient temperature of 30°C were assumed. For additional
information see H.E. King, "Rectangular Waveguide Theoretical CW Average Power Rating," IRE
Transactions PGMTT-9, pp 349-357, July 1961.
