We present the results of studying the emissive properties of molybdenum cathodes with deposed diamond films at strong currents, as well as the dependences of these properties on the deposition regimes and the structure of diamond films. The emissive properties of the films are determined by analyzing the output parameters of a high-power compressor of microwave pulses, which is based on diamond-coated cathodes. It is shown that the use of such cathodes allows one to increase the emission current and the amplification factor of the microwave compressor.
