Shielded Low-Noise Amplifier Front-End Module with GPS/GNSS/BDS Pre-Filter

The SKY65725-81 is a shielded front-end module (FEM) with an integrated low noise amplifier (LNA) and pre-filter 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).

The pre-filter provides the low in-band insertion loss and integrated notch filtering for excellent rejections of the cellular, PCS, and WLAN frequency bands. The SKY65725-81 uses surface-mount technology (SMT) in a 1.6 x 1.6 x 0.8 mm Multi-Chip Module (MCM) package, which allows for a highly manufacturable and low-cost solution.
