SKY55951-11

Sky5® GNSS L1 + L5 Dual-Frequency Low-Noise Amplifier Front-End Module with Post-Filter

The SKY55951-11 front-end module (FEM) features an integrated L1 low-noise amplifier (LNA) and post-filter along with an L5 low-noise amplifier (LNA) and post-filter designed for Global Navigation Satellite System (GNSS) receiver applications. The SKY55951-11 is part of our Sky5® product portfolio. The device provides high linearity, excellent gain, a high 1 dB input compression point (IP1dB), and a superior noise figure (NF).

The post-filter provides excellent rejections of the cellular, PCS, and WLAN frequency bands. The SKY55951-11 uses surface-mount technology (SMT) in a Multi-Chip Module (MCM) package, which allows for a highly manufacturable and low-cost solution.
