Key Features
- Manufacturer: Skyworks Solutions Inc.
- Part Number: SE5503A-R
- Device Type: 2.4 GHz Wi-Fi/Zigbee RF front-end module
- RF Function: Integrated front-end module combining PA, LNA, RF switch and matching for 2.4 GHz wireless links
- Frequency Range: 2.4 GHz ISM band, typically 2.4 GHz to 2.5 GHz or 2.4 GHz to 2.483 GHz depending on SE family
- Wireless Standards: 802.11b/g/n, Bluetooth, Zigbee/802.15.4 or proprietary 2.4 GHz operation depending on module
- Transmit Path: Integrated power amplifier; SE260x/SE262x WLAN variants are high-output 2.4 GHz FEM families
- Receive Path: Integrated LNA or bypass/receive path on supported SE front-end module variants
- Control Interface: Digital control pins select Tx/Rx, bypass or antenna paths depending on exact module
- Package / Case: Compact QFN front-end module package; suffix -R indicates reel ordering
- Design Notes: Confirm output power, PA supply voltage, control truth table and antenna matching for the exact SE module.
Applications
RF and microwave signal-chain boards, wireless infrastructure, radar modules, satellite/ISM systems and receiver/transmitter support circuits.
Replacement sourcing, shortage support and legacy RF module builds where the exact suffix, package and RF behavior must match the original BOM.
Quality & Sourcing
Antrex Electronics can support sourcing for SE5503A-R through available stock checks, BOM consolidation and alternative-lot review. For RF and microwave components, packaging condition, date code, MSL handling and original labeling should be checked before shipment.
For project builds, repair support or shortage coverage, Antrex Electronics can coordinate visual inspection, package verification and third-party testing when required. This helps buyers manage risk when sourcing discontinued, legacy or hard-to-find RF ICs and modules.
