The EWD-900-HDTC is a fully integrated half duplex wireless FSK data transceiver that is suitable for the US (902-928 MHz) or UK(868MHz). The basic design of the transceiver can be scaled from 300MHz to 1GHz, allowing operation in countries around the world.

The transceiver can operate on 128 channels in the 902-928MHz US unlicensed band, and 20 channels in the 868-870 MHz unlicensed UK band.

The transceiver contains built-in data encoding and decoding, simplifying the interface and software of the host microcontroller. It can send and receive data using either Manchester encoding or un-encoded from a UART. Data rates of 0.6 to 76.8 kbit/second are supported.

A typical circuit will consist of a low-cost microcontroller, a power source, and an antenna. The transceiver requires no external RF components with the exception of a 50 ohm antenna. The EWD-900-HDTC can transmit and receive data over distances of 300-500 feet.

On-board EEPROM memory stores a unique 48-bit identification number that can be used in networking applications for address resolution. It also stores calibration information about the module, eliminating the need for manual tuning adjustments. Several features of this module are patent pending.

The patent-pending DIP style package is designed to support manual and automatic assembly. The module's small size, .70' x .70" x .20" , and low cost, make it ideal for high volume applications.
