SILICON LABS ETRX3585-LRS

The Telegesis ETRX3585-LRS and ETRX3585HR-LRS ZigBee long range modules have been designed to be easily integrated into another device and to provide a fast, simple and low-cost wireless mesh networking interface. The Telegesis ETRX3 series modules are based on the Silicon Labs ZigBee compliant platform consisting of the single chip family of EM3585 SoCs combined with the ZigBee PRO compliant EmberZNet meshing stack. The ETRX3585-LRS and ETRX3585HR-LRS modules represent an ideal platform for custom firmware development in conjunction with the Silicon Labs ZigBee development kits. No RF experience or expertise is required to add this powerful wireless networking capability to your products. The ETRX3585-LRS and ETRX3585HR-LRS offer fast integration opportunities and the shortest possible time to market for your product. The main building blocks of the ETRX3585-LRS and ETRX3585HR-LRS are the single chip EM3585 SoC from Silicon Labs, a SiGe SE2432L frontend module combining a Power Amplifier with a Low Noise Amplifier, a 24MHz reference crystal and RF front-end circuitry optimized for best RF performance. The modules are available with on-board antenna or alternatively a U.FL connector for attaching external antennae. Modules with the U.FL connector are identified by the “HR” suffix. The LNA and RF power amplifier of the LRS devices improve the output power by 12dB and the sensitivity by 5dB which will increase the range by approximately 700% relative to the standard devices (where local regulations permit the use of the maximum output power).

• The Telegesis ETRX3585-LRS and ETRX3585HR-LRS modules are low power 2.4GHz ZigBee modules with an added frontend module (SiGe SE2432L) containing both PA and LNA for highest possible link budget.
• Based on the latest Ember EM3585 family of single chip ZigBee solutions, the new long-range modules are footprint compatible with the entire Telegesis ETRX3 family, thus representing a drop-in replacement for all applications where a high link budget is required.
