Abstract: In a multi-layer substrate module receiving from an external earth node (20) supply of a reference potential (Vss) for grounding, a plurality of ground lines (170-1, 170-2, 170-3) are provided respectively corresponding to a plurality of internal circuits (210, 220, 230). Moreover, a common node (Ncmn) for coupling the ground lines (170-1, 170-2, 170-3) is provided in an insulating layer (105C) of the multi-layer substrate module. The common node (Ncmn) is electrically coupled to the earth node 20 through a ground pin terminal 204 shared by the plurality of internal circuits (210, 220, 230). Preferably, the common node (Ncmn) is provided in the lowest insulating layer of the multi-layer substrate module. Thus, parasitic inductance of the portion through which an earth current flows, that is, the portion common to the plurality of internal circuits (210, 220, 230), can be suppressed with a small number of ground pin terminals. Accordingly, the inflow phenomenon of the earth current between the plurality of internal circuits (210, 220, 230) is prevented, enabling stable operation.

Abstract: A linear amplifier includes a variable attenuator and a phase shifter for modifying the amplitude and phase of an input signal to compensate for amplitude and phase distortion caused by non-linear characteristics of a high-powered amplifier utilized in a microwave band communications system. An amplitude comparator and a phase comparator compare the amplitudes and phases of input and output signals of the linear amplifier circuit to develop control signals for controlling the operation of the variable attenuator and phase shifter. The elimination of digital signal processing circuitry allows increased speed of operation that is essential for use in the microwave bands.

Abstract: In a modulation system using an amplitude and a phase of a carrier wave as information such as a QPSK system, a modulation device modifies an input signal series to compensate the nonlinear characteristics of an amplifier located at a later stage, and provides a carrier wave modulated by the modified signal series to the amplifier. A first arithmetic circuit obtains an amplitude and a phase of an input signal by calculation. A ROM is set with correction data corresponding to the calculated amplitude so as to compensate the nonlinearity of the amplifier. A modification value generating circuit and a RAM output an amount of compensation so as to further modify the correction data according to part of an output signal from the amplifier to compensate amplifier characteristic changes due to temperature variations and the like. A second arithmetic circuit provides a signal series produced from the modified amplitude and phase to a quadrature modulator.
