Abstract
PURPOSE:To block excessive input to an MIC device board and to protect the electronic components, by adding a high frequency signal RF detection circuit, control circuit and RF switch circuit for an input circuit. CONSTITUTION:An RF signal is inputted from an input plug 1a, and RF detection circuit 5 always detects the input power in the RF signal inputted to an MIC module and transfers a detection signal to a control circuit 6. The circuit 6 discriminates normal and excessive input of the input power and transfers a signal to block the RF signal to an RF switch circuit 7 only at the excessive input. The circuit 7 keeps transmitting the RF signal to the MIC device board 3 if the signal of RF signal block from the circuit 6 is not transmitted, but if the RF signal block signal is transmitted, since the RF signal is blocked through the operation of the RF switch, no RF signal is transmitted to the board 3, allowing to protect the electronic components for the board 3 against an excessive input signal.
