Abstract

A communication device system includes a communication device () and a reception power monitoring device (). The communication device () includes a reception processing unit () that outputs a signal intensity voltage (Vin) in accordance with a signal level of a received signal, and a monitoring terminal signal generator circuit () that generates a monitoring terminal signal (Vout) by current amplification of a level shift voltage generated by shifting a level of the signal intensity voltage (Vin) by an offset voltage (Voff) corresponding to a voltage value of a power supply voltage of an external device. The reception power monitoring device () includes a constant voltage generator circuit that outputs a constant voltage from the monitoring terminal signal (Vout), and a voltage converter circuit that operates based on the constant voltage and outputs a display level indication signal reflecting a voltage level of the monitoring terminal signal (Vout).
