This article is about ENW-89818C2KF RF Transceiver Modules in terms of its application field and working principle. ENW-89818C2KF is a low cost, highly efficient, and compact RF transceiver module, designed for industrial wireless applications, such as machine-to-machine, professional mobile radio (PMR) and meter reading. This RF transceiver module supports a wide range of frequency bands and have two outputs, TX and RX, to provide a complete data link.

ENW-89818C2KF is an integral part of a complete communications system, with a comprehensive range of features for enhanced performance and operation. It is an innovation in wireless technology that offers improved performance and reliability in communications systems.

ENW-89818C2KF is an ultra low power, high-performance RF transceiver module that supports a wide range of industrial applications. It operates at 900/1800, 400/800 or 470/700 MHz, depending on the specific model.It has a high output power of up to 42 dBm, high receive sensitivity of -53dBm and a low-noise floor. Its high sensitivity means that it can receive signals from farther distances than other transceivers.

The ENW-89818C2KF transceiver module features a half-duplex, half-duplex with transmit and receiver channels, allowing for simultaneous and bidirectional communication. It also features FSK, GFSK, GMSK and OOK modulation, along with complete modulation algorithms for operating on narrow bandwidths. Furthermore, this transceiver module supports a carrier sense multiple access protocol.

The ENW-89818C2KF transceiver module is designed to meet the needs of both local area network and wide area network (WAN) applications. For local area networks, the transceiver is designed with an effective range of up to 1000m, with optimal power level of up to 42 dBm. For WAN applications, the transceiver operates with a typical range of up to 500m, with optimal power of up to 27 dBm in low band.

The working principle of ENW-89818C2KF transceiver module is based on a bi-directional communication process. The receiver and transmitter module share the same frequency channel. At the beginning of the transmission, the transmitter module first sends a single tone signal. The receiver module then searches for the carrier and tunes the channel to the same frequency. It then sends a signal back to the transmitter module, indicating that the channel is ready for data communication. The transmission and reception data are then sent and received over the same channel. If the data is not properly received, the receiver module sends an acknowledgement back to the transmitter module, which then sends the data again. This process ensures reliable data transfer between the two modules.

In summary, ENW-89818C2KF RF Transceiver Modules are designed for industrial wireless applications, such as machine-to-machine, professional mobile radio (PMR) and meter reading. It supports a wide range of frequency bands and provides a complete data link. It features a half-duplex, half-duplex with transmit and receiver channel, allowing for simultaneous and bidirectional communication. The working principle of ENW-89818C2KF is based on a bi-directional communication process, which ensures reliable data transfer between the two modules.
