Overview
The BGU7005, also known as the GPS1101M, is a Low Noise Amplifier (LNA) designed by NXP USA Inc. for Global Navigation Satellite System (GNSS) receiver applications. This component is housed in a plastic leadless 6-pin SOT886 package, which is extremely small and suitable for compact designs. The BGU7005 is optimized for use in modern cellular handsets, adapting to the changing environment caused by co-habitation of different radio systems. It is engineered for low power consumption and optimal performance even in the presence of jamming signals from co-existing cellular transmitters.
