DL-RTS4463M is a Wireless Data Transparent Transmission Module designed base on Siliconlabs' new generation chip SI4463, it is ultra-high performance with micro-power. This Wireless Transmission Module has high integration, and low power consumption, which adopts spread spectrum communication technology, and has the characteristics of long transmission distance, extremely high sensitivity, super anti-interference ability, flexible and convenient parameter configuration and so on.
The module adopts highly efficient cyclic interleaving error correction coding, which greatly improves anti-interference and sensitivity. It provides multiple channel selections, and support parameters online modification, such as serial port rate, transceiver frequency, transmit power, RF rate and other important parameters. The working voltage of DL-RTS4463M module is 2.1V-3.6V, and the working voltage of 3.5V-5.5V can be customized. In the receiving state, it only consumes 15mA current.
The module uses single-chip architecture, combined with a cost-effective low-power main control chip, electronic switches, high-precision chip crystal, etc., to form a Data Transmission radio frequency unit with excellent performance. There are four modes of the module: any mode can be switched arbitrarily. In the 1SEC cycle polling wake-up power-saving mode, the receiving current consumes only tens of microamperes, and a 3.6V / 3.6AH battery can work for several years, which is very suitable for battery-powered system.
