SKY65601-477LF

1.575 GHz GPS/GNSS/BDS Low-Noise Amplifier

Please note: SKY65601-477LF is being discontinued and is not recommended for new designs. The suggested replacement is SKY65624-682LF

The SKY65601-477LF is a Microwave Monolithic Integrated Circuit (MMIC) front-end Low Noise Amplifier (LNA) designed for Global Positioning System/Global Navigation Satellite System/ Beidou Navigation Satellite System (GPS/GNSS/BDS) receiver applications. The device provides high linearity, excellent gain, a high 1 dB Input Compression Point (IP1dB), and a superior Noise Figure (NF). All critical matching components are embedded inside the device. No external matching components are required.

The SKY65601-477LF is optimized to operate at 1.559 and 1.610 GHz, which makes it ideal for GPS/GNSS/BDS radio receiver applications.

The SKY65601-477LF is fabricated using advanced SiGe BiCMOS technology. The LNA uses Surface Mount Technology (SMT) in the form of a 2.0 x 1.3 mm Dual Flat No-Lead (DFN) package, which allows for a highly manufacturable and low-cost solution.
