GFSK modulation/demodulation, multi-channel operation, high bandwidth efficiency and anti-blocking performance make DRF4463D20-043A1 modules easy to realize the robust and reliable wireless link.The module can be configured to work in different channels. It adopts the high efficient looped interleaving EDAC (Error Detection and correction) coding with coding gain up to 3dB which keeps in advance in error correction and coding efficiency over normal FEC (Forward Error Correction) coding. Because of its high reliability in correction, modules can filter error and fake information automatically and realize truly transparent wireless link, which makes DRF4463D20-043A1 very suitable in the rigid communication environment. DRF4463D20-043A1 integrates two 256 bytes buffer. When the buffer is empty, users can transfer nearly 256 bytes data per time and even limitless data transfer can be achieved as long as RF data rate is configured to be faster than UART data rate (MCU to RF module). DRF4463D20-043A1 provides standard UART/TTL interface. Users can choose seven data rates and three parity checks which make DRF4463D20-043A1 possibly tailor-made for different applications. DRF4463D20-043A1 operates at 2.2~3.6V with low power consumption. The module can work in four different modes which are very suitable for battery powered-up applications. Please note that this package includes 2pcs modules and 2pcs antenna.
