PURPOSE:To allow a repeater which converts plural reception frequencies into intermediate frequency signals, switches and re-edits them and converts them into plural transmission frequencies, to keep a frequency interval of transmission frequencies with high accuracy equal to a frequency interval of receiver frequencies. CONSTITUTION:Frequencies received by plural reception sections 21-2n are converted into intermediate frequencies by generating local oscillated frequencies by phase synchronization oscillators 21A-2nA in the different phase synchronization degrees by using an output of a 1st original oscillator 6 as a reference signal. After they are re-edited by a switching circuit section 3, while plural transmission sections 41-4n mix outputs from a 2nd original oscillator 7, phase synchronization oscillators 41A-4nA generate a local oscillating frequency in different phase synchronization degrees using an output of the 1st original oscillator 6 as a reference signal to execute frequency conversion. |
