ETRX357-LRS

The ETRX357-LRS is Not Recommended for New Designs.

The ETRX357-LRS module has a footprint of just 25.0x19.0x3.8 for both standard and PA/LNA versions which represent a 40% reduction in size compared to the ETRX2 module. They will be available with either an onboard antenna or a Hirose U.FL connector to allow connection of external antenna. The ETRX357-LRS module adds the new SiGe SE2432 front-end, containing both LNA+PA for the highest possible link budget. The ETRX357-LRS is a low power 2.4 GHz Zigbee Radio module integrating a 2.4 GHz, IEEE 802.15.4 compliant transceiver with up to 192of flash, 12 of RAM, and many advanced peripherals. The ETRX357-LRS utilizes an efficient architecture that exceeds the dynamic range requirements imposed by the IEEE 802.15.4-2003 standard by over 15 dB. The integrated receive channel filtering allows for robust co-existence with other communication standards in the 2.4 GHz spectrum, such as IEEE 802.11 and Bluetooth.
