A7005CGHN1/T1AGBFJ

Overview

The NXP A7005CGHN1/T1AGBFJ is a SiGe:C Low Noise Amplifier (LNA) MMIC designed for GPS, GLONASS, Galileo, and Compass (BeiDou) receiver applications. It operates within the full GNSS L1 band from 1559 MHz to 1610 MHz. The device features a noise figure of 0.85 dB and provides 16.5 dB gain. It includes adaptive biasing to suppress strong cellular and WLAN transmit signals, improving linearity under jamming conditions. The component requires only one external matching inductor and one decoupling capacitor, housed in a small 6-pin leadless SOT886 package measuring 1.45 x 1.0 x 0.5 mm.

Feature Summary

• SiGe:C technology with 0.85 dB noise figure and 16.5 dB system-optimized gain
• Adaptive biasing dynamically suppresses strong cellular/WLAN jamming signals
• Operates on supply voltage of 1.5 V to 3.1 V with power-down current < 1 uA
• Small 6-pin leadless SOT886 package (1.45 x 1.0 x 0.5 mm)
• Integrated temperature stabilized bias and ESD protection > 2 kV HBM

Applications

• Smart phones and feature phones
• Tablet PCs and Personal Navigation Devices (PNDs)
• Digital Still Cameras (DSCs) and Digital Video Cameras (DVCs)
• RF front-end modules and complete GPS chipset modules
• Automotive theft protection systems

Procurement Notes

Verify the specific ordering suffix /T1AGBFJ against manufacturer documentation to confirm tape-and-reel packaging specifications and standard product orientation. Confirm availability status as the base BGU7005 model may be subject to end-of-life or discontinuation notices. Ensure compatibility with existing PCB footprints for the SOT886 package.

Selection Notes

Select this component for designs requiring minimal external components and high linearity in environments with co-existing cellular transmitters. The adaptive biasing feature is critical for maintaining sensitivity during high jamming power levels. Verify that the required 16.5 dB gain and 0.85 dB noise figure meet the link budget requirements for the target GNSS application.

Part Context

This part belongs to the BGU700x/BGU8007 family of SiGe:C GPS LNAs. These devices are engineered to offer the smallest footprint in the market while providing industry-first dynamic suppression of strong interferers. The family targets mobile and automotive applications where space constraints and signal integrity are paramount.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Check for direct replacements within the BGU700x series or consult NXP for updated recommended alternatives if the base model is discontinued.
