ETRX357

The ETRX357 is Not Recommended for New Designs.

The ETRX357 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 an external antenna. A link budget of 105 dB on the standard ETRX357 module gives excellent performance and RF power. The ETRX357 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 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.
