摘要： To provide an amplifying device which is reduced in size, weight and cost and which can improve the distortion compensation performance. In the amplifying device, input signals are each subjected to digital orthogonal modulation using an IF and further to offset rotation processing in digital orthogonal modulators, then bifurcated into a main signal system and a control system, and detection of a power value is performed at an IF band in a power detecting section of the control system. Therefore, offset rotation processing of the input signals in the power detection is not required, so that a structure for matching phases of a multi-carrier signal and a power value signal is not required, resulting in improving the distortion compensation performance without using an analog delay line.

摘要： With an amplifier configured by including Doherty-type amplifier sections 21 to 25, the area of the circuits is reduced so that the size reduction is achieved. Moreover, the properties of the Doherty-type amplifier sections (Doherty properties) are stabilized against any environmental change of humidity and temperature. As an example, the permittivity of a substrate 3 configuring one or more of quarter wavelength lines 23 and/or 24 included in the Doherty-type amplifier sections 21 to 25 is increased compared with the permittivity of a substrate 2 in a close range. As another example, a line portion forming an output circuit of a carrier amplifier in the Doherty-type amplifier sections is configured by using a substrate material being physically stable against either or both of any change observed in the humidity and the temperature.
