ATF-36163-BLKG

Overview

The ATF-36163-BLKG is a low-noise amplifier (LNA) manufactured by Broadcom Limited, designed for high-performance RF applications. It operates within a frequency range of 0.5 GHz to 4.0 GHz and utilizes a surface-mount SOT-363-6 package. The device provides a typical gain of 21 dB while maintaining a noise figure of 1.8 dB at 2 GHz. It requires a supply voltage of 3 V and draws a quiescent current of 15 mA. Key linearity specifications include a P1dB compression point of 17 dBm and an OIP3 of 29 dBm. The component is constructed using silicon technology and supports single-channel operation with a maximum operating temperature of +150°C.

Feature Summary

• Integrated low-noise amplification optimized for minimal signal degradation in receiver front-ends
• Broadband operational capability spanning from 0.5 GHz to 4.0 GHz for versatile frequency coverage
• High linearity performance characterized by elevated output third-order intercept points
• Compact surface-mount packaging facilitating automated assembly and space-constrained designs

Applications

• Wireless local area network (WLAN) receiver front-ends
• Global Positioning System (GPS) and navigation receivers
• Cellular base station and mobile handset RF chains

Procurement Notes

Verify the specific ordering suffix and manufacturer lot codes against official Broadcom documentation to ensure authenticity. Confirm that the component meets required RoHS compliance standards for the target market. Check for obsolescence notices or last-time buy notifications as availability may be restricted. Ensure proper electrostatic discharge handling procedures are followed during storage and installation.

Selection Notes

Select this component when a balance of low noise figure and high linearity is required across a broad microwave frequency range. Evaluate the trade-off between the 1.8 dB noise figure and the 21 dB gain relative to system sensitivity requirements. Consider the SOT-363-6 package constraints for thermal management and PCB layout. Verify power supply stability given the 15 mA quiescent current draw to maintain consistent performance.

Part Context

This part belongs to Broadcom's portfolio of RF amplifiers, specifically targeting wireless communication infrastructure and consumer electronics. It complements other broadband LNAs in the series by offering a standardized pinout and performance profile suitable for multi-band designs. The BLKG suffix typically denotes specific tape-and-reel packaging configurations used in high-volume manufacturing environments.

Replacement Considerations

Consult official Broadcom substitution guides for verified equivalents. Cross-reference pin compatibility and electrical parameters such as noise figure and gain flatness before considering alternative manufacturers.
