摘要： PROBLEM TO BE SOLVED: To efficiently attain the transmission and reception of data in a state that antenna sensitivity is satisfactory in a PDA (portable information terminal) equipment incorporating a communicating function. SOLUTION: This device is provided with a rotating mechanism 18 for supporting an RF antenna 17 for operating the transmission and reception of data at two positions, that is, a horizontal position and a vertical position to the display screen of a device main body 11. Also, a position detection switch 19 is set in the neighborhood of a rotating part, and the antenna position is detected. When it is detected that the RF antenna 17 is present at the vertical position to the display screen, a mode for enabling the transmission/reception of data is set, and when it is detected that the RF antenna 17 is present at the horizontal position, a mode for disabling the transmission/reception of data is set. Thus, only when the RF antenna 17 is present at the vertical position, the data communication can be executed, and it is possible to avoide the execution of the data communication in a state that the RF antenna 17 is present at the horizontal position, and antenna sensitivity is deteriorated.

摘要： PROBLEM TO BE SOLVED: To reduce the influence of variance of the output frequency of a synthesizer that is caused by the variance of power voltage due to the ON/OFF operations of a transmitting part in the time division multiplex communication by providing the regulator of the synthesizer separately from the regulators which are used in other blocks. SOLUTION: A 1st regulator 2 is prepared to convert the voltage of a battery 1 into the desired voltage and supplies this voltage to a transmitting part 3, a receiving part 4 and a base band signal processing part 6 together with a 2nd regulator 7 which is placed separately from the regulator 2 and converts the voltage of the battery 1 into the desired one to supply it to a synthesizer 5. The input voltage of the regulator 7 is always varied by the ON/OFF operations of the part 3 and this variance, however, can be reduced by the ripple rejection performance of the regulator 7. Thus the stable voltage can always be supplied to the synthesizer 5 despite the ON/OFF operations of the part 3.

摘要： PURPOSE: To reduce the distortion signals of a base band generated by adjacent channel signals. CONSTITUTION: From the cut-off frequency of a base band filter 610 at the poststage of the frequency converter 609 of a receiver constituted of a direct conversion system, secondary distortion is detected in a secondary distortion signal detection circuit 614 composed of a filter 612 whose passing band is a frequency within the double of the cut-off frequency and a signal strength detection circuit 613 at the poststage of the filter 612. When the deterioration of a reception state due to the secondary distortion generated from interference signals is generated, shifting to a slot other than the slot where the interference signals are present is performed and an influence on the reception state by the interference signals is avoided.

摘要： PURPOSE:To make the control circuit of the power amplifying part compact and monolithic and to compensate the linear amplifier characteristic for the change of the amplifying characteristic by controlling the bias of the power amplifying part so that the power level difference detected by a detecting means to zero. CONSTITUTION:The power level of the frequency component of the upper and lower band wave extracted by band pass filters 5 and 7 is detected by power level detection parts 9 and 11. A power level comparison part 13 outputs the power level difference of the output signal to a terminal T9 for the power level of the output signal to a terminal T7 to a terminal T11. A bias control part 15 outputs a bias control signal to the bias terminal T1 of the power amplifier part 1 based on the control function defined by the power level to be outputted to the terminal T11. The bias control signal controls the bias of the power amplifier part 1. The power level in the pass frequency range of the band-pass filter of the upper band wave and the power level in the pass frequency range of the band pass filter of the lower band are set to the absolute power level lower than the specified value.

摘要： PURPOSE:To increase impedance with an inductance inside an IC, the inductance provided with an adjustment element on a substrate side and the inductance of an element for connecting them. CONSTITUTION:At the time of connecting the IC 11 and a substrate 13 by a bonding wire, inconsistency is generated between them by a connection position, a loop length and the degree of tension, etc. The inductance 14 is provided in the IC 11 so as not to let the inconsistency reach a transistor 12. At the time, as an element value for reducing influence, the value twice as much as or more as the input and output impedance of the transistor is defined. Also, so as to avoid the inconsistency due to change and the difficulty of the change of the element value inside the IC 11, the inductance 16 whose loss is lower than the inductance 14 is used on the side of the substrate 13 and it is made variable. Further, so as to supply a DC voltage to the IC 11, a connection element 15 for connecting the IC 11 and the substrate 13 is provided and the element 15 becomes an undefined element at the time of mounting the IC 11. Thus, a function as a matching circuit for higher harmonic and the basic wave of a desired high frequency is attained.
