GPS/GLONASS/Galileo/Compass Low-Noise Amplifier

The SKY65623-682LF is a Microwave Monolithic Integrated Circuit (MMIC) front-end low-noise amplifier (LNA) designed for Global Navigation Satellite System (GNSS) radio receiver applications. The device provides low current consumption, excellent gain, and a superior noise figure (NF). Output matching components are embedded inside the device. Only one external input matching inductor is required.

The SKY65623-682LF is optimized to operate at 1559 to 1606 MHz, which makes it ideal for GPS/GLONASS/Galileo/Compass radio receiver applications.

The SKY65623-682LF is fabricated using advanced SiGe BiCMOS technology. The LNA uses surface-mount technology (SMT) in the form of a 0.8 × 0.8 mm Quad Flat No-Lead (QFN) package, which allows for a highly manufacturable and low-cost solution.
