摘要：A detector for detecting changes in the output level of an amplifier included in,for example, a mobile communication signal. A first detecting circuit produces a detectedvoltage having linearity against low output levels of the amplifier. A second detectingcircuit produces a detected voltage which is linear against high output levels of theamplifier. The detected voltages from the first and second detecting circuits are mixed bya mixer in a predetermined ratio. Even when the output level of the amplifier changesover a broad dynamic range, the detector detects the changes with accuracy.
