PROBLEM TO BE SOLVED: To provide a power measuring device with a high degree of accuracy in measuring signals with a high peak-to-average electric power ratio. SOLUTION: An input means 12 for receiving an input RF signal is provided with a low-electric power sensor path 14, which includes a first laminated diode means 18, for detecting a relatively low-electric power input RF signal. In addition, an impedance circuit network 20 including serially connected attenuating resisters R1 and R2 is provided between the input means 12 and a ground. A high-electric power sensor path 22 including a second laminated diode means 24 and connected between the attenuating resistors R1 and R2 and the ground for detecting an attenuated relatively high-electric power input RF signal is further provided. The sensor diodes of the first and second laminated diode means are operated within a square-law area.
