2.4G Wireless Transceiver Module with CC2500 Chip and PA

Designed base on TI-Chipcon’s CC2500 wireless transceiver chip, DL-24PA is a compact, cost-effective, remote wireless transceiver module. This 2.4G wireless Module is widely used in the fields of smart home, toys, model airplane and near range digital transmission control. Sensitivity up to -104dbm, maximum transfer rate up to 500Kbps, output power through register configuration range -30dbm to 20dbm.

The module has integrated all radiofrequency related functions, and users can easily develop wireless products with stable performance and high reliability directly, which will extremely shorten the development cycle without in-depth understanding of RF circuit design SMD and DIP interface modes are adopted, but manual welding is required due to different thermal expansion coefficient of the black glue and the binding wire inside. Small module size makes it easy to use in portable products and compatible with DL-24D 2.4G RF Module without PA.
