Abstract

Besides a time constant circuitthat imposes a frequency limit on a wireless signal detected by a power detecting circuitat a preset time constant Ta, there is provided a time constant circuitthat imposes a frequency limit on the wireless signal at a time constant Tb greater than the time constant Ta. When the signal level of an intermittent operation signal supplied from a signal input terminalis H level or when a threshold processing circuitdecides that the level of the wireless signal is higher than a threshold Th, a logic unitsupplies a control signal that instructs starting to the power detecting circuit, time constant circuitsandand threshold processing circuitsand
