PROBLEM TO BE SOLVED: To eliminate noise emission to peripheral circuits caused by a discontinuous point of a phase by preventing the occurrence of phase discontinuous point in a SAT transmission signal. SOLUTION: A SAT transmission signal output section is provided with a PLL phase-locked loop circuit B27. The PLL phase-locked loop circuit B27 oscillates by itself at a frequency other than it is instructed in advance from a base station when a mobile terminal is not receiving the SAT signal instructed to itself, but it oscillates at a frequency synchronous with the SAT signal when it is not receiving the SAT signal. |
