| Zusammenfassung: | The utility model relates to a low noise frequency reducer of an integrated satellite positioning system. The utility model carries out power amplification on received radio frequency signals through a group of amplifiers, the amplified radio frequency signals are then mixed with oscillation frequency generated by a local oscillator and the original radio frequency signals are converted into intermediate frequency signals. In addition, the power of intermediate frequency signals is amplified by at least one amplifier. A satellite positioning system antenna is in charge of receiving a satellite's positioning signals, and the positioning signals and the amplified intermediate frequency signals are output together by a transmission line. |
