Abstract:
An amplifier circuit with a multi-space structure for high frequency amplification, comprising:a Gunn diode installed in a space between two metal plates of a certain distance from each other; a circulator which revolves input waves and determines transmission direction; a first non-radiative dielectric waveguide which is connected to the circulator, sending the input waves from the input terminal to the circulator; a second non-radiative dielectric waveguide which also is connected to the circulator, sending the input signals from the circulator to the Gunn diode and sending the amplified signals from the Gunn diode back to the circulator; and a third non-radiative dielectric waveguide which is connected to the circulator, sending the amplified signals, which come into the circulator through the second non-radiative dielectric waveguide, to the output terminal; wherein the non-radiative dielectric waveguides are installed in a space between two metal plates of different size, forming the multi-space structure.
