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

The SKY65704-22 is an integrated, Front-End Module (FEM) with an integrated Low Noise Amplifier (LNA) and pre-filter designed for Global Positioning System/Global Navigation Satellite System (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 LNA is fabricated using advanced GaAs pHEMT technology. The GPS 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 SKY65704-22 uses Surface Mount Technology (SMT) in the form of a 2.8 x 2.5 mm Multi-Chip Module (MCM) package, which allows for a highly manufacturable and low-cost solution.

An integrated low-band notch filter is incorporated in the SKY65704-22 to improve 2nd Order Intermodulation (IMD2) performance.

Please note: SKY65704-22 being discontinued and is not recommended for new designs.
