The operation of Gunn diode with series concatenated InP_0.7As_0.3 and In_0.4Ga_0.6As active regions was analyzed in terms of the two-temperature intervalley electron transfer model. The energy and frequency characteristics of the diodes differing in the type of cathode metallic contact were obtained (barrier height is 0.04 eV). The output characteristics of the diode with two active regions and a blocking metallic cathode were found to result from the complex interplay between the physical processes occurring simultaneously in the two regions. The highest output power flux was estimated to be ~40 kW/cm² at a frequency of 42 GHz and a generation efficiency ~20%. The diode with an antiblocking metallic cathode contact operates as a heterocathode diode, i.e. a generation of current oscillations is provided exclusively by the In_0.4Ga_0.6As active region.
