AW5005DNRZ

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

The AW5005 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 AW5005 can be close to the antenna, requires only one input matching inductor for L1 band while additional output matching capacitor and inductor are needed for L2/L5 band, and reduces assembly complexity and the PCB area, enabling a cost-effective solution.The AW5005 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 3.6V. All these features make AW5005 an excellent choice for GNSS LNA as it improves sensitivity with low noise figure and high gain, provides 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.
