摘要： A small-sized distortion compensation circuit is disclosed. In a semi-conductor element having three terminals, its gate is used as an input terminal. One of the drain and source is used as an output terminal, and the other is grounded. This structure does not need a conventionally used circuit comprising a complicated combination of distributors, couplers and attenuators, enabling the circuit to be smaller.

摘要： Since the loss of the conventional microwave device is large, when this device is applied to the microwave component, there are problems; for example, a low-noise amplifier, the noise figure is degraded, and when applied to a high-output amplifier, output and efficiency may be decreased. In particular, in the high-output amplifier of over 100W class, heat generation at a capacitor which forms the microwave device increases, which causes a problem that the reliability of the microwave device may be decreased. A structure is formed to include a capacitor loaded between two high impedance lines the length of which has ¼ wavelength in the desired frequency band and the characteristic impedance is higher than 50Ω.
