Research on passing CW power capacity of cylindrical box type window
The formula for calculating the threshold of average transmitting power of cylindrical TE11 mode window is revised by accurate deduction.A practical method for calculating the temperature increment of the dielectric disk in cylindrical box type window is given. Meanwhile, a typical cylindrical box type window is calculated and used as an example to discuss the power capacity, the special harmfulness and elimination of ghost mode resonance when the window is used to transmit high power CW.It is showed that, in L band, general cylindrical box type windows may be used to transmit 120～150kW CW and the possible relative bandwidth is 14% or so, in the case of elimination of the ghost mode.
