RFX2401C

Product Overview

RFX2401C from Skyworks Solutions Inc. is a 2.4 GHz ISM/WLAN RF front-end module used in RF front-end designs that need integrated transmit, receive, switching or low-noise signal-chain functions. This description focuses on practical RF parameters such as band coverage, PA/LNA path behavior, control requirements and package compatibility.

The exact orderable suffix should be matched before purchase because RF front-end devices often vary by band plan, pinout, reel format, qualification grade and control-state truth table.

Key Features

• Manufacturer: Skyworks Solutions Inc.
• Part Number: RFX2401C
• Device Type: 2.4 GHz ISM/WLAN RF front-end module
• RF Band / Frequency Range: 2.4 GHz ISM band, commonly 2400 MHz to 2483.5 MHz depending on exact family
• Transmit / PA Path: Integrated PA for ZigBee/Bluetooth/WLAN transmitter boost and harmonic filtering on selected variants
• Receive / LNA Path: Integrated LNA receive path with bypass or switch routing depending on SE/RFX suffix
• Output Power / Linearity: Typical modules target +20 dBm to +26 dBm class output power depending on part number and modulation
• Control / Bias: Low-voltage CMOS control pins for TX/RX/bypass/antenna states
• System Impedance: 50 Ω RF interface where specified by the device reference design or data sheet
• Package / Case: Compact QFN/MCM front-end module package, suffix defines reel or sample format
• Operating Temperature: RF front-end module temperature range is suffix-specific; verify industrial or automotive grade before sourcing
• Design Notes: Confirm exact SE/RFX device data sheet for PA output power, LNA NF, harmonic filtering and switch-state truth table.

Applications

Bluetooth, ZigBee, 802.15.4, 2.4 GHz Wi-Fi and short-range IoT radio modules.

Also suitable for engineering replacements, shortage support and BOM consolidation where the same RF band, package footprint and control interface must be maintained.

Quality & Sourcing

Antrex Electronics can support sourcing for RFX2401C through available stock checks, BOM consolidation and alternative-lot review. For RF front-end modules, packaging condition, date code, MSL handling, reel labeling and moisture exposure 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 reduce risk when sourcing hard-to-find or lifecycle-sensitive RF front-end components.
