POWER AMPLIFIER Russian patent published in 2024 - IPC H03F3/04 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used in receiving-transmitting and measuring radio equipment operating at frequencies, including the microwave range. Result is provided by introducing into the power amplifier two in-series connected inductors and a capacitor, while the values of the main elements satisfy the ratios for real part ReẎ_M(ω) and for imaginary part ImẎ_M(ω) input conductivity Ẏ_M(ω), which take place at the connection point of the collector of the reverse p-n-p conductivity transistor and the base of the forward n-p-n conductivity transistor: ImẎ_M(ω) ≈ ImẎ_M; ReẎ_M(ω) ≈ ReẎ_M, where ω is cyclic frequency, ImẎ_M and ReẎ_M are quasi-constant imaginary and real parts of input conductivity between cascades on these transistors.

EFFECT: wider input matching band of the amplifier with a standard path while simultaneously increasing its transmission coefficient.
