High-power Cherenkov type microwave device based on the unmatched dielectrical liner (maser) is studied by the methods of the effective linear theory. All theoretical investigations of amplification and generation of microwaves are made by the model of the well-known experimental device. Electrodynamical properties of using a slow-wave structure are calculated in the absence and in the presence of an electron beam inside it. It is shown that the existence of mismatches at the ends of the structure converts it into a passing resonator. A device based on the latter has corresponding resonance properties which determine the discrete generation spectrum and its starting conditions. As a result generation band of the device consists of a series of separate generation lines. The calculated bandwidth is compared with its experimental value. The process of generation band tunability is studied too. In conclusion some features of the considered device are discussed in detail.
