摘要： In a signal receiving circuit of a direct conversion system applied with a semiconductor integrated circuit for radio communication having a PLL requiring a clock signal, an LNA requiring low-noise receiving characteristics, and others, a variable coupling line is provided between clock signal buffers and at an input stage of the PLL, so that coupling between the variable coupling line and an input terminal of the LNA and coupling between the variable coupling line and a GND terminal of the LNA are made equal to each other at frequencies of higher harmonic waves of a clock signal. When the input terminal and the GND terminal of the LNA are excited at the same phase, since no output occurs at an output terminal of the LNA, an output of the LNA does not contain any higher harmonic wave of a clock signal.

摘要： A wireless communication system uses a transmission power detection circuit. The transmission power detection circuit has excellent linearity of detection output for transmission output power and can obtain detection output not having temperature dependence. The transmission power detection circuit has rectifying detection part that includes plural amplifiers connected in series and obtains detection output by taking out rectified outputs from emitters of input transistors of amplifiers of individual stages and synthesizes them. A compensation voltage generating circuit has a dummy amplifier having a construction similar to the amplifiers constituting the rectifying detection part and a coefficient circuit that changes output of the dummy amplifier at a specified ratio, and generates voltage for compensating temperature characteristics. Also included is an addition/subtraction circuit that obtains detection output free of temperature dependence by subtracting compensation voltage generated in the compensation voltage generating circuit from output voltage of the rectifying detection part.
