19、ir 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.

20、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 71C, 1:1 VSWR, and an ambient t
21、emperature of 30C 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. TABLE III.
