Overview
The BGU7004, also known as the GPS1103M, is an AEC-Q100 qualified Low Noise Amplifier (LNA) designed for Global Navigation Satellite System (GNSS) receiver applications. It is manufactured by NXP USA Inc. and is packaged in a small, 6-pin SOT886 (6-XFDFN) package. This LNA is optimized for low power consumption and optimal performance in the presence of jamming signals from co-existing cellular transmitters. It covers the full GNSS L1 band, from 1559 MHz to 1610 MHz, and requires only one external matching inductor and one external decoupling capacitor for operation.
