Product Overview

The SKY65902-21 is a high-performance Front-End Module (FEM) designed for Global Positioning System/Global Navigation Satellite System (GPS/GNSS) receivers. Integrated with a Low-Noise Amplifier (LNA) and pre/post-filters, it utilizes advanced GaAs pHEMT technology to deliver high linearity, low noise figure, and excellent out-of-band rejection. Supporting both differential and single-ended outputs, it is ideal for satellite navigation devices requiring superior signal sensitivity and interference resistance.

Key Features

• Exceptional Signal Amplification: Provides 12 dB typical small-signal gain in GNSS bands with a low Noise Figure (NF) of 2 dB, enhancing weak-signal reception capabilities.
• High Linearity & Interference Resistance: Third-order Input Intercept Point (IIP3) of +2 dBm effectively suppresses cellular, WLAN, and other band interferences, ensuring stable operation in complex electromagnetic environments.
• Low Power & Ease of Use: Operates from a single DC supply (1.8–3.6 V) with typical current consumption of 5 mA (active mode) and 0.5 µA (shutdown mode), requiring minimal external components for simplified circuit design.
• Integrated Design & Compact Size: Housed in a 3.2 x 2.5 mm 12-pin MCM package (MSL3 rating), with internally matched 50 Ω input/output impedance, eliminating the need for external matching networks and saving PCB space.
• Reliability & Environmental Compliance: Halogen-free and RoHS compliant, with 2000 V ESD protection (HBM test), suitable for rigorous manufacturing and operational environments.

Technical Specifications

Typical Applications

• In-Vehicle Navigation Systems: Integrated into automotive GPS receivers, the module enhances signal sensitivity in urban canyons or tunnels, ensuring precise positioning through high gain and low noise design.
• Portable Navigation Devices: Suited for handheld GPS units and drones, its compact size and low power consumption extend battery life while resisting interference from cellular and Wi-Fi signals.
• IoT Positioning Terminals: Used in asset tracking and wearable devices, supporting global band reception with simplified front-end design, reducing system cost and power drain.
