The present invention relates to a GPS low-noise amplifier module and, more specifically, to a GPS low-noise amplifier module which comprises a front-end SAW connected between an antenna and a low-noise amplifier, the low-noise amplifier connected between the front-end SAW and a rear-end SAW to amplify a signal received from the antenna, and the rear-end SAW connected between the low-noise amplifier and a high-frequency transceiver, and in which a band blocking filter is connected to at least one among between the antenna and the front-end SAW, between the front-end SAW and the low-noise amplifier, and between the low-noise amplifier and the rear-end SAW. A band blocking signal and noise can be effectively blocked while amplifying a band pass signal of the GPS low-noise amplifier module. The characteristics of signal transmission can be improved while reducing an insertion loss of the GPS low-noise amplifier module.
