摘要： PROBLEM TO BE SOLVED: To obviate an external circuit such as a signal path changeover switch when bidirectionally performing frequency conversion using one frequency converter. SOLUTION: A base of a bipolar transistor 1 connected to an RF terminal 13, an IF terminal 9 and an LO terminal 6 is connected with a power source 16 via a power supply switch 11. When the power supply switch 11 is turned on and an RF signal and an LO signal are inputted to the bipolar transistor 1, a mixed signal of the both is outputted as an IF signal. When the power supply switch 11 is turned off, the bipolar transistor 1 is operated as two diodes connecting a base terminal 4 and an emitter terminal 2 and connecting the base terminal 4 and a collector terminal 3 and when the IF signal and the LO signal are inputted, they are mixed by the diodes and an RF signal is outputted. Thus, unidirectional frequency conversion has a plus conversion gain and the signal is inputted or outputted in each direction of frequency conversion in each of the terminals.

摘要： PROBLEM TO BE SOLVED: To provide a multi-mode radio apparatus which makes a circuit scale small by sharing frequency dividers and combining them upon setting the number of frequency division and by eliminating a phase error of an output.
SOLUTION: A frequency dividing portion 22 comprises the frequency divider 19 to frequency-divide an output of a local oscillator, the frequency divider 20 to frequency-divide an in-phase local oscillation signal of the frequency divider 19, and a dummy circuit 21 connected to an output terminal of an orthogonal local oscillation signal of the frequency divider 19. The output of the frequency divider 19 is used for a modulation-demodulation at a first frequency band operation and the output of the frequency divider 20 is used for the modulation-demodulation at a second frequency band operation. The frequency divider 19 is for common use in the first and second frequency bands, but the in-phase local oscillation signal and the orthogonal local oscillation signal which are the outputs of the frequency divider 19 keep a phase difference at the first frequency band operation by making the dummy circuit be the same circuit as an input amplifier of the frequency divider 20.
