Skyworks has introduced the SKY65623-682LF, a low noise amplifier (LNA) designed for applications such as wearables, asset trackers, navigation devices, action cameras and more. This discrete LNA is optimized to operate from 1559 to 1606 MHz, has a very low current (1 mA @ 1.8 V supply) and single power supply (1.5 to 3.6 V range) for design flexibility and simplicity. The device’s broad frequency range covers GPS L1, GLONASS, Galileo and Compass navigation systems and it minimizes external components thereby reducing the bill of materials for OEMs. The SKY65623-682LF comes in an extremely compact form factor (5L QFN 0.8 x0.8 mm package), ideal for low-power Internet of Things (IoT) devices.
