摘要： The present invention concerns a radio circuit including a local oscillator, a first receive frequency converter, a frequency divider and a demodulator. A receive signal and an output of the local oscillator are input to the first receive frequency converter. The receive signal is converted into a first intermediate signal by the first receive frequency converter, and the first intermediate frequency signal is input to the demodulator. The output of the local oscillator is frequency-divided by the frequency divider and also input to the demodulator. The signal converted into the first intermediate frequency is demodulated into a baseband signal by the demodulator.

摘要： The invention provides a high-speed PLL frequency synthesizer in which the frequency of a reference signal can be made larger than a frequency interval of an external output with a simple configuration. An n-th harmonic of an output of a voltage-controlled oscillator is caused to pass through a band pass filter. The frequency of an output of the band pass filter is divided by M in a variable frequency divider. The phase of an output of the variable frequency divider is compared with that of the reference signal in a phase comparator. An output of the phase comparator is smoothed by a loop filter. The output of the voltage-controlled oscillator is controlled by an output of the loop filter. The fundamental wave of the output of the voltage-controlled oscillator is caused to pass through another band pass filter, and then output to the outside. At this time, the frequency of the reference signal is n times a frequency interval of the fundamental wave of the output of the voltage-controlled oscillator.

To achieve the above object, in the invention, of a conductive antenna element, a part of a length of a substantially half-wavelength is used as a monopole part (1), and is disposed along the inside of a housing at the upper end of a portable wireless unit.

The inverted-F antenna part (2) is disposed parallel to the upper end of the portable wireless unit (6). One end of the inverted-F antenna part (2) is connected to the ground plate (5) through an earthing point (3) provided at one end. A feeding point (4) is provided spaced from the earthing point by a predetermined distance. With such an arrangement, there is no need of using an impedance matching circuit. The construction of the portable wireless unit is simplified. High antenna gain is secured under various use conditions.
