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

The SKY65724-11 is a front-end module (FEM) with an integrated low noise amplifier (LNA) and prefilter designed for Beidou Global Positioning System/Global Navigation Satellite System (BDS/GPS/GNSS) receiver applications. The device provides high linearity, excellent gain, a high 1 dB input compression point (IP1dB), and a superior noise figure (NF).

The GPS pre-filter provides the low in-band insertion loss for excellent rejections of the cellular and WLAN frequency bands. The SKY65724-11 uses surface-mount technology (SMT) in the form of a 1.1 x 1.5 mm Multi-Chip Module (MCM) package, which allows for a highly manufacturable and low-cost solution.

The LNA matching inductor is placed outside the module to enable performance optimization.
