Device for detecting the power of a radio frequency signal

摘要

The present invention describes a device for detecting the power of a first signal (Vout) at a given frequency. Said device (10) comprises first means (1) suitable for detecting the envelope (Vi) of said first signal (Vout) and second means (2) coupled to said first means (1) and suitable for generating a second signal (Vdet) proportional to the average of the envelope (Vi) detected. The second signal (Vdet) is proportional to the square root of the average power (Poutm) of the first signal (Vout). <IMAGE>
