摘要： A radio communication apparatus is designed for at least first and second radio communication formats which prescribe first and second desired IF pass bandwidths respectively. The first desired IF pass bandwidth is greater than the second desired IF pass bandwidth. The radio communication apparatus includes an IF band-pass filter processing a first IF signal into a second IF signal and having a predetermined pass bandwidth corresponding to the first desired IF pass bandwidth. A demodulator recovers a first baseband signal from the second IF signal generated by the IF band-pass filter. A baseband filter processes the first baseband signal generated by the demodulator into a second baseband signal. The first baseband signal generated by the demodulator is selected as a final output signal when the first IF signal is of the first radio communication format. The second baseband signal generated by the baseband filter is selected as a final output signal when the first IF signal is of the second radio communication format.

摘要： A frequency synthesizer consists of a voltage-controlled oscillator and a frequency division and distribution section. The frequency division and distribution section, which splits an oscillation signal of the voltage-controlled oscillator into a transmission modulation local oscillation signal and a reception second local oscillation signal while frequency-dividing the oscillation signal of the voltage-controlled oscillator, includes two pairs of frequency dividers and two switches. The frequency division numbers of the two pairs of frequency dividers are so set as to accommodate all the combinations of mobile communications systems and the transmission modulation local oscillation signal/reception second local oscillation signal. The two switches are switched in accordance with a mobile communications system for which a mobile transceiver is operating. The two local oscillation signals are input to a quadrature modulator and a quadrature demodulator, respectively.

摘要： A fraction part control circuit of a frequency synthesizer apparatus including a PLL circuit is of a plural-n-th-order delta-sigma modulator circuit for controlling a fraction part of a number of frequency division to a variable frequency divider of the PLL circuit. An adder adds data of the fraction part to an output data from a multiplier and outputs the resultant data to a quantizer through a second-order integrator. The quantizer quantizes input data with a quantization step and outputs the quantized data to the multiplier through a feedback circuit. The quantized data is used as data of the controlled fraction part. The multiplier multiplies data from the feedback circuit by the quantization step and outputs the resultant data to the adder. The fraction part control circuit periodically changes the data of the fraction part, thereby setting a frequency of an output signal from a VCO according to an average value of the period.
