GPS/GLONASS/Galileo/BDS Low-Noise Amplifier

The SKY65611-11 is a Microwave Monolithic Integrated Circuit (MMIC) front-end low-noise amplifier (LNA) designed for Global Positioning System/Global Navigation Satellite System (GPS/GLONASS)/Galileo and Beidou Navigation Satellite System (BDS) receiver applications. The device provides high linearity, excellent gain, a high 1 dB Input Compression Point (IP1dB), and a superior noise figure (NF). Output matching components are embedded inside the device. Minimal input matching components are required.

The SKY65611-11 is optimized to operate at 1559 to 1610 MHz, which makes it ideal for GPS/GLONASS/Galileo/BDS radio receiver applications.

The SKY65611-11 is fabricated using advanced SiGe BiCMOS technology. The LNA uses surface-mount technology (SMT) in the form of a 1.1 x 0.9 mm Dual Flat No-Lead (DFN) package, which allows for a highly manufacturable and low-cost solution.
