Ultra-Low Noise Amplifier for Global Navigation Satellite Systems (GNSS)

AW15045 is a Low Noise Amplifier designed for Global Navigation Satellite Systems (GNSS) as GPS, GLONASS, Galileo and Compass. With on-chip DC blocking capacitors at RFIN and RFOUT. The AW15045 can be close to the antenna, requires only one external input matching inductor, and reduces assembly complexity and the PCB area, enabling a cost-effective solution.

AW15045 with patented Smart Linearity Technology (SLT) achieves ultra-low noise figure, high linearity, high gain, over a wide range of supply voltages from 1.5V up to 3.3V. All these features make AW15045 an excellent choice for GNSS LNA as it improves sensitivity with low noise figure and high gain, provide better immunity against out-of-band jammer signals with high linearity, reduces filtering requirement of preceding stage and hence reduces the overall cost of the GNSS receiver.
