Wireless UART RF Modules
Wireless UART modules have a standard UART interface and have a built-in protocol. The designer can usually tweak some aspects of the protocol, but the basic structure is defined inside the module. The main advantage of these modules is that the protocol is done. Simply write the data to be transmitted to the serial port and the module handles the transmission and reception automatically. This significantly reduces the processor code development. However; the protocol is common to all users, so some potential for different systems to cross-talk exists. This can be dealt with by the application inside the data payload.

Amplified HumPRO™ Series Long Range RF Transceiver Module
Long Range, Pre-Certified 900MHz Transceiver
The Amplified HumPRO™ Series transceiver adds a front-end amplifier block to the popular HumPRO™ Series. This boosts transmitter output power to +25dBm and receiver sensitivity to -108dBm. This 133dB link budget gives the Amplified HumPRO™ Series transceiver a range of up to 12.9km (8 miles) while supporting a data rate of 115.2kbps. The module is below $18 in volume. The 900MHz module has achieved FCC and IC modular certification.

HumPRO™ Series RF Transceiver Module
Frequency Hopping Digital Data RF Transceiver Module
The HumPRO™ Series is a Frequency Hopping Spread Spectrum (FHSS) transceiver designed for the reliable transfer of digital data. It has a very fast lock time (<60ms typ) so that it can quickly wake up, send data and go back to sleep, saving power consumption in battery-powered applications that have strict power budgets. Built on the Linx Hummingbird platform, the module is below $10 in volume, effectively competing with discrete designs. Two versions are available with FCC and Industry Canada certifications as well as a non-certified version that is smaller and lower cost.

DTS & EUR Series RF Transceiver Modules
Wireless UART RF Transceiver Module
The DTS and EUR Series combine a low power 868MHz or 900 MHz wireless transceiver with a powerful multipoint-to-multipoint protocol controller to form a complete wireless communication solution capable of replacing wires in almost any RS-232/422/485 application. The module has a Universal Asynchronous Receiver Transmitter (UART) serial interface that can be connected directly to microcontrollers, RS-232 converters or USB adaptors. The module automatically handles all radio functions resulting in a UART-to-antenna wireless link.

250 Series RF Transceiver Module
High Power Wireless UART RF Transceiver Module
The 250 Series RF transceiver module is designed for reliable bi-directional transfer of digital data over distances of up to 4 miles (6.4km, line of sight). Operating in the 902 to 928MHz frequency band, the module is capable of generating +23.5dBm into a 50-ohm load and achieves an outstanding typical sensitivity of -105dBm. This high output power gives the module exceptional range and also helps overcome noisy environments at shorter ranges.
