波管形トランジスタ増幅器。In an ultra-high frequency amplifier that includes a transistor mounted on a coaxial section and has waveguides at its input and output sections, compensates for the slope of the frequency characteristics of the transistor along the coaxial section connected to the input terminal or output terminal of the transistor. A coaxial low-pass filter or a radial band reflection filter is connected, the end is high-frequency terminated with an absorber, a DC bias is applied from the inner conductor, and orthogonal branches are made from the inner end of the coaxial filter. Waveguides are connected, and one of the waveguides is short-circuited with a variable short-circuit part, and the other is connected to the amplifier input end or output end through a high-pass filter or a band-pass filter that is an inverse circuit to the coaxial type filter. A waveguide type transistor amplifier characterized in that:
