Wireless Transceivers

AIR for Bluetooth Low Energy

Anaren offers a range of low power RF transceiver modules for wireless solutions developers worldwide that leverage Texas Instruments silicon and extensive suite of software development tools. Anaren AIR modules offer the best performance-to-size ratio in the industry. Based on the Texas Instruments CC2541 chipset, our Bluetooth Low Energy modules allow customers to easily add BLE connectivity to their products. Harnessing elite processing and memory while fitting on a tiny footprint, these modules provide the best design flexibility available. On top of that, these modules are 100% radio frequency tested in production and are FCC/IC certified, saving you from those expensive costs and fast-tracking you towards deployment.

The A2541x24* is a high-performance radio module that incorporates the Texas Instruments CC2541 SOC, either with a CC2590 Range Extender (A2541E24x) or without a range extender (A2541R24x). Pre-certified to FCC/IC, this module also includes either an integral antenna (24A) or a connector (24C) that accepts a U.FL monopole antenna, all in one of the industry’s smallest package: 11x19x2.5mm.
* The commodity classification for the A2541R24x10 and A2541R24x20 modules is: 5A992a per CCATS G152766. This is a non-restrictive classification, requiring a license for only Cuba, Iran, North Korea, Sudan, and Syria.
