Boron-nitride high-power duplexing devices

The design of the cylindrical pre-TR is a compromise between the amount of power than can be safely absorbed by the window and the low-level insertion loss. Once the low-level insertion loss and recovery time of a duplexer have been fixed, the feasibility of the device depends on dissipating the heat generated in the plasma discharge without exceeding the critical temperature of the dielectric user to contain the gas.
