Signal amplification device and signal amplification integrated equipment

The utility model is suitable for a communications field provides a signal amplification device and signal amplification integrated equipment. The signal amplification device include: frequency channel detecting element can detect the judgement to incoming signal to output frequency channel testing result, the frequency modulation unit carries out gate control and output signal to incoming signal, multifrequency section signal amplifying unit, including being used for two kind at least different frequency channels to carry out the signal amplification module of signal amplification, laggard line output is enlargied with the incoming signal that frequency modulation unit gating goes out to the signal amplification module. Still disclose a signal amplification device, except containing above -mentioned signal amplification device, still included independent device power. The embodiment of the utility model provides an in, through the two -way signal amplification device who has the compatible adjustable functio
