The mechanism of conversion from the kinetic energy of electron beams to electromagnetic wave energy is investigated in the two-stream amplifier. It is shown that the optimal efficiency of the amplifier scales according to AV/V for relativistic electron beams and (AV/V) 2 for nonrelativistic electron beams, where AV is the axial velocity difference in the two beams and V is the mean axial beam ...

..4bstract—A novel ultrabroad-band amplifier configuration suitable for GaAs FET’s has been developed. The developed amplifier circuit operates as a capacitor-resistor ( C–R ) coupled mnpfifier circuit in the lowfrequency range in which IS21 I for the GaAs FET’s is constant. It also operates as a lossless impedance matching circuit in the microwave frequency range in which IS21 I for the GaAs F...
