Introduction

A Low Noise Amplifier designed for Global Navigation Satellite Systems (GNSS) as GPS, Beidou, GLONASS, Galileo and Compass. With on-chip DC blocking capacitors at RFIN and RFOUT, it can be close to the antenna. It requires only one external input matching inductor for GPS L1, which can reduce assembly complexity and the PCB area, enabling a cost-effective solution.

With patented Smart Linearity Technology (SLT), it achieves low noise figure, high linearity, high gain, over a wide range of supply voltages from 1.5 V up to 3.1 V. All these features make it an excellent choice for GNSS LNA as it improves sensitivity with low noise figure and high gain, provides better immunity against out-ofband jammer signals with high linearity, reduces filtering requirement of preceding stage and hence reduces the overall cost of the GNSS receiver.

It is available in a small lead-free, RoHS-Compliant, DFN 1.1 mm X 0.7 mm X 0.37 mm-6L package.
