The SKY65725-11 is a shielded front-end module (FEM) with an integrated low noise amplifier (LNA) and pre-filter designed for GNSS (GPS, Beidou) receiver applications. The module operates from 1559 to 1606 MHz and provides high linearity with a small signal gain of 16.5 dB, and has a noise figure of 1.8 dB. It requires a single DC supply voltage from 1.1 to 2.85 volts.
The pre-filter provides low in-band insertion loss and excellent rejection of the cellular, PCS, and WLAN frequency bands.
The SKY65725-11 is available in a surface-mount 9-pin Multi-Chip Module (MCM) that measures 1.6 x 1.6 x 0.75 mm. An additional filter is also incorporated in the SKY65725-11 to improve performance in the presence of a Band 13 blocker.
