WIRELESS MODULE SHARING POLARITY INVERSION CIRCUIT WITH OTHER CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a wireless module that shares a polarity inversion circuit with other circuit and has a reduced circuit scale resulting in space saving and power saving. SOLUTION: The wireless module shares a polarity inversion circuit with another circuit and is characterized in that an AC signal oscillation circuit required in the polarity inversion circuit 10 is shared with an oscillation circuit using the output of a reference frequency divider circuit 11A in a phase synchronizing circuit 11 so as to reduce the required space and power consumption.
