PURPOSE:To prevent mutual interference and to made a terminal equipment small by connecting a transmission/reception means and a control means via an optical transmission means or providing a battery to the transmission/ reception means and the control means respectively and using them separately. CONSTITUTION:A mobile radio terminal equipment consists of an antenna 1 through which a high frequency signal is sent/received, a transmission section converting a voice and a data into a high frequency signal, a base band section 3 receiving a high frequency signal from the antenna 1 and converting it into a signal and a control section 7 using an output section 3a and an input section 3b to control the band section 3. Through the constitution above, a power is supplied from a battery 9a to the band section 3 and power is supplied to the control section 7 by a battery 9b. Moreover, an optical converter 5b converting the high frequency signal into a light is provided in the control section 7 for the transmission of a control signal between the control section 7 and the band section 3, and an optical converter 5a converting the light signal into the high frequency signal is provided in the band section 3 and the converters 5a, 5b are communicated by an optical signal 5c. Thus, the optical signal 5c is detected by a photodiode PD, from which only a high frequency component is outputted. |
