A bias voltage is applied via a first resistance to the base of a first transistor, and a radio frequency signal is input via a first capacitor to the base of the first transistor. The bias voltage is applied via a second resistance to the base of a second transistor. The bias voltage is applied via a third resistance to the base of a third transistor, and the radio frequency signal RF is input via a third capacitor to the base of the third transistor. A first band rejection filter is provided between the base of the first transistor and the base of the second transistor. A second band rejection filter is provided between the base of the second transistor and the base of the third transistor. The collectors of the first to third transistors are connected in common and the emitters thereof are all grounded.

A bias current to be supplied to an amplification circuit 60 is drawn out of a collector of a transistor Q11 of a bias circuit 10. The drawn-out bias current is input to a base of a transistor Q13 via an attenuation filter F2 and is output from an emitter of the transistor Q13 in the state where the voltage thereof is reduced by a level corresponding to Vbe. The attenuation filter F2 is conducted in a DC manner, and attenuates a component of a frequency fH(=2ft−fr) defined by a transmission frequency ft and a receiving frequency fr of a radio frequency signal. The bias current output from the emitter of the transistor Q13 is supplied to the amplification circuit 60 via an attenuation filter attenuates a component of a frequency fL(=|fr−ft|).

This invention is directed to a destination guidance system for providing presentation information that contains guidance pertaining to movement from a place of departure to a destination on the basis of structure information and guidance information on the premises of a building or construction. The presentation information contains both information of the entire three-dimensional structure, and detailed information, and a three-dimensional movement and normal two-dimensional movement in the presentation information are presented by different methods. Also, this invention is directed to a destination guidance data acquisition system for acquiring structure information and guidance information on the premises of a building, which are used by the destination guidance system. The destination guidance data acquisition system inputs and compiles information of a three-dimensional structure on the basis of a plan view of the building to support acquisition of the detailed information.
