Skyworks Solutions of Woburn, Massachusetts, has launched the SKY65623-682LF low-noise amplifier (LNA) for applications including wearables, asset trackers, navigation devices, and action cameras.
The SKY65623-682LF is a Microwave Monolithic Integrated Circuit (MMIC) front-end LNA designed for GNSS radio receiver applications. The device is designed to provide low current consumption (1mA @ 1.8V supply), optimal gain, and a superior noise figure (NF). Output matching components are embedded inside the device. Only one external input matching inductor is required.
It is optimized to operate at 1559 to 1606 MHz, which makes it well suited for GPS/GLONASS/Galileo/BeiDou 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 millimeter Quad Flat No-Lead (QFN) package, which allows for a highly manufacturable and low-cost solution, according to the company. The broad frequency range spans GPS L1, GLONASS, Galileo and Compass (BeiDou) navigation systems, and minimizes external components, reducing the bill of materials for OEMs.
