SE2547A-R

Overview

The SE2547A-R is a high-performance RF front-end module designed for wireless applications supporting IEEE 802.11a/b/g/n standards. It operates within the 2.4 GHz to 2.5 GHz and 4.9 GHz to 5.875 GHz frequency bands. The device integrates a 2.4 GHz power amplifier, a 5 GHz power amplifier, transmit/receive switches, diplexers, and a TX filter. It utilizes a 32-LGA (5x5) package with an exposed pad. The module requires a 3.3 V operating supply voltage and draws a maximum operating current of 250 mA. It supports data rates up to 11 Mbps and functions within a temperature range of 0°C to +85°C.

Feature Summary

• Integrates dual-band power amplifiers for 2.4 GHz and 5 GHz operations alongside transmit/receive switching and filtering components.
• All RF ports are internally matched to 50 Ω impedance to simplify circuit design.
• Includes integrated power detectors for each output path to enable precise signal monitoring.

Applications

• Wireless LAN devices compliant with 802.11b/g standards
• Wireless LAN devices compliant with 802.11a/n standards
• Integrated Wi-Fi modules requiring compact front-end solutions

Procurement Notes

Verify component authenticity through authorized Skyworks Solutions distributors or certified partners. Confirm that the received units match the specific SE2547A-R marking and package type. Check for RoHS compliance documentation as required by regional regulations. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent package damage prior to assembly.

Selection Notes

Select this component for designs requiring a single-chip solution for dual-band Wi-Fi connectivity. It is suitable for applications needing integrated PA functionality without external matching networks. Consider the 32-LGA package dimensions for PCB layout constraints. Verify that the system power supply can deliver the required 3.3 V at up to 250 mA peak currents during transmission phases.

Part Context

This part belongs to Skyworks' SiGe series of RF front-end modules. It is engineered to reduce board space and component count in mobile and IoT devices. The module consolidates multiple discrete RF components into a single surface-mount package. It supports standard wireless communication protocols commonly used in consumer electronics and networking hardware.

Replacement Considerations

Public records indicate the SE2547A-R status is obsolete. Designers should consult Skyworks official documentation for qualified replacement parts or next-generation alternatives compatible with 802.11a/b/g/n standards and similar package footprints.
