High-performance FSK Transceiver Module with Si4463 Chip


DL-RTS4463 was designed base on Silicon Labs' Si4463 wireless transceiver chip. It is a compact,low-power, long-distance wireless transceiver module. The chip launched by Silicon Labs is mainly set to 315MHz, 433MHz, 868MHz, 915MHz and other special frequency bands of the national networks. The sensitivity can reach -126dbm, the maximum transmission rate can reach 1000Kbps, and the output power can range from -20dbm to + 20dbm through the register configuration.This module integrates all RF-related functions. Users do not need to have a deep understanding of RF circuit design; they can use this RF module to easily develop wireless products with stable performance and high reliability, shortening the product development cycle.

This RF transceiver module adopts single-chip architecture, and the periphery adopts high-precision crystal, high-Q Murata inductor, small volume but high-capacity filter capacitor. All SMD components are used, and the interface is encapsulated with standard pitch stamps, which is conducive to the development of compact systems and the application of SMT in mass production.
