HIGH FREQUENCY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a high frequency device which prevents backtalk from occurring. SOLUTION: Intermediate frequency 64a outputted from the mixer 53 is set so that it may become larger than a value obtained by subtracting the value of minimum frequency 16a from two times of maximum frequency 16b of a high frequency signal 16. Thus, the occurrence of the backtalk can be prevented.
