FSK Wireless Transceiver Module with TI CC1101 B
Product Description
FSK Wireless Transceiver Module base on TI-Chipcon's CC1101 Transceiver Chip
DL-RTC1101B (Miniature version) was designed base on TI-Chipcon' S CC1101 wireless transceiver chip. It is a compact, long-distance, high-performance wireless transceiver module. The chip launched by TI-Chipcon is mainly set to 315MHz, 433MHz, 868MHz, 915MHz and other special frequency bands of the national networks. The sensitivity can reach -114dbm, the maximum transmission rate can reach 500Kbps, and the output power can range from -30dbm to + 10dbm through the register configuration.
This wireless module integrates all RF-related functions. Users do not need to have a deep understanding of RF circuit design; they can use this module to easily develop wireless products with stable performance and high reliability, shortening the product development cycle.
There are 2 interface modes (SMD and DIP) been adopted, which can not only meet customers' SMT application, but also realize transverse and longitudinal welding through 2.0mm standard stitch arrangement. The compact size of the module is convenient for portable products, and it can well meet the requirements of low-power system by combining with low-power MCU.
