BGU8103X

The NXP Semiconductors BGU8103X is an ultra-low current, Low-Noise Amplifier (LNA) specifically designed for Global Navigation Satellite System (GNSS) receiver applications. It operates across the full GNSS L1 band, from 1559 MHz to 1610 MHz, providing a typical gain of 17.5 dB with a low noise figure of 0.80 dB. This MMIC is optimized for performance in environments with co-existing radio systems, such as cellular handsets, by adapting its bias current to mitigate jamming signals.

The BGU8103X features a supply voltage range of 1.5 V to 3.1 V and consumes a typical supply current of 1.2 mA. It includes integrated features such as supply decoupling, temperature-stabilized bias, and DC blocking at both RF input and output, simplifying external component requirements. The device is housed in a small 6-pin leadless package (6-XFDFN) with dimensions of 1.1 mm x 0.7 mm, making it suitable for space-constrained designs. ESD protection is provided on all pins.

Key electrical specifications include an input 1 dB compression point of -16 dBm and an out-of-band IP3i of -8 dBm. The amplifier operates within a temperature range of -40 °C to 85 °C. Its SiGe:C technology enables a transit frequency of 180 GHz. The BGU8103X is an ideal choice for applications like smartphones, tablets, digital cameras, and complete GNSS modules requiring high performance and low power consumption.
