摘要： A variable gain amplifier includes a plurality of element circuits each having an output current that increases at a constant rate with a change in a variable control voltage, voltages that increase in steps of the change being respectively supplied to the plurality of element circuits as their reference voltages and the control voltage being supplied to each of the plurality of element circuits, multipliers for multiplying the output currents from the plurality of element circuits by one another, and an amplifier for carrying out a variable gain amplification based on an output current from the multipliers. The variable gain amplifier can suppress any change in the characteristics thereof due to temperature compensation of the characteristics and variations in manufacturing of transistors, and carry out a linear gain control operation on the control voltage when the gain is expressed in a logarithm.

摘要： In a &pgr;/2 phase shifter, first and second signals and first and second inverted signals are produced based on input signals. The first and second signals have the same amplitude and are out of phase from each other, and the first and second inverted signals respectively correspond to the first and second signals with their respective phases inverted. A first output signal is produced by adding the first signal and the second signal, and a second output signal is produced by adding the first signal and the second inverted signal. Since the first and second signals have the same amplitude, the first output signal and the second output signal respectively correspond to diagonal lines of a rhombus formed by a vector representing the first signal and a vector representing the second signal. Accordingly, the phase difference between the first and second output signals of the &pgr;/2 phase shifter is accurately set to &pgr;/2 even when the phase difference between the first and second signals is not &pgr;/2.
摘要翻译：在π/ 2移相器中，基于输入信号产生第一和第二信号以及第一和第二反相信号。第一信号和第二信号具有相同的幅度并且彼此异相，并且第一和第二反相信号分别对应于其相应相位反转的第一和第二信号。通过将第一信号和第二信号相加来产生第一输出信号，并且通过将第一信号和第二反相信号相加来产生第二输出信号。由于第一和第二信号具有相同的幅度，所以第一输出信号和第二输出信号分别对应于由表示第一信号的矢量和表示第二信号的矢量形成的菱形的对角线。因此，即使当第一和第二信号之间的相位差不是pi / 2时，pi / 2移相器的第一和第二输出信号之间的相位差被精确地设置为pi / 2。
