2.4G RF Transceiver Module with TI Chipcon's CC2500 Design

Designed base on TI-Chipcon's CC2500 wireless transceiver chip, DL-24TRGC is a compact, cost-effective, remote wireless transceiver module, which is widely used in smart home, toy aeromodelling and close-range data transmission control fields. Sensitivity up to -105dbm, maximum transfer rate up to 500Kbps, output power through register configuration range from -30dbm to +1dbm. The module is integrated with all RF related devices and has PCB onboard antenna, so excellent RF performance can be obtained without additional antenna configuration.

This module uses standard 8PIN output. RSSI and low power mode can be set up effectively in the application to reduce the cost. You 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. Manual welding is required due to different thermal expansion coefficient of the black glue and the binding wire inside.
