Signal strength detecting device and related method

Image Number 2 for United States Patent #8121572.

A signal strength detecting device of a communication system is disclosed. The signal strength detecting device is coupled to a frequency down mixer of the communication system and the frequency down mixer is used for receiving and converting a first signal to a second signal whose frequencies are lower than frequencies of the first signal. The signal strength detecting device comprises a frequency up converter for receiving and converting the second signal to a third signal whose frequencies are higher than the frequencies of the second signal and a detecting unit for detecting strength of the third signal and generating a signal strength indicator to the communication system according to a detecting result corresponding to the strength of the third signal, wherein the signal strength indicator represents the strength of the first signal received by the frequency down mixer.
