Reference signal intensifier, and satellite signal emitter

This invention provides a reference signal intensifier. It utilizes the functions of a filter and an amplifier to enable a reference signal with a larger and more stable input power dynamic range. In addition, it reduces the influence due to the variation of temperature on the circuit. The reference signal intensifier comprises a power source, a first low pass filter, a second low pass filter, a band-pass filter, and a signal amplifier. The first low pass filter connects with a reference frequency signal for eliminating a first frequency of the reference frequency signal. The second low pass filter connects with the first low pass filter for eliminating the harmonic waves of the reference frequency signal or the frequency signals higher than the reference frequency signal. The band-pass filter connects with the second low pass filter for eliminating a second frequency of the reference frequency signal. The signal amplifier amplifies the input power dynamic range usable by the reference frequency signal and re
