GNSS Low-Noise Amplifier Front-End Module with integrated Pre-Filter and Post-Filter

The SKY65933-11 is a front-end module (FEM) with an integrated low-noise amplifier (LNA), pre-filter, and post-filter designed for Global Navigation Satellite System receiver applications. The device fully integrates all input and output matching components to simplify PCB designs. The pre-filter and post-filter provide low in-band insertion loss and excellent rejection for the cellular, PCS, and WLAN frequency bands. The device also features a single-pin enable and an extremely low shut-down current when disabled.

The SKY65933-11 is optimized to operate at 1559 to 1606 MHz, which makes it ideal for GPS/GLONASS/Galileo/Compass/QZSS radio receiver applications.

The SKY65933-11 uses surface-mount technology (SMT) in the form of a 2.5 x 2.5 mm Multi-Chip Module (MCM) package, which allows for a highly manufacturable and low-cost solution.
