Generation on broadband radio pulses by a new type reflex triode with a virtual cathode

Results are presented of the development and experimental study of a new type reflex triode with a virtual cathode. In this device, a discharge excited along a ferroelectric surface is used as a source of electrons and loop antennas are used for emitting radiation. Generation of broadband radio pulses with a central frequency of ∼300 MHz and power of ∼80 W is achieved.
