Product overview
The A8520E24A91 is a high-performance, FCC/IC-certified radio
module that incorporates the Texas Instruments CC8520 transceiver
chip and the CC2591in the industry’s smallest package (11 x 19 x
The A8520E24A91 module is a surface mount module integrating a
8520 PurePath™ wireless audio transceiver with the CC2591
PA/LNA device ,for increased range, and an integral antenna. The
module incorporates a crystal, the required RF matching and filtering
for FCC/IC compliance as well as filtering on all digital lines for good
noise reduction and sensitivity. The modules operate in the global
non-licensed 2.4GHz ISM/SRD frequency band. These radio modules are ideal for achieving low power wireless connectivity without
having to deal with extensive Protocol, RF, antenna design and regulatory compliance, allowing quick time to market. The modules are
100% tested to provide consistent performance.
The A8520E24A91 has an RoHS-compliant ENIG finish and is packaged on tape and reel for high-volume automated manufacturing.
