Semtech expanded its RFIC transceiver platform with the new SX1235, a fully integrated sub-GHz RF transceiver that provides ETSI category 1 compliance with 6 dB regulatory margin. ETSI category 1 compliance is the highest transceiver rating for European regulations and is required for safety-critical wireless applications such as social alarms and healthcare monitoring.
The IC features +20 dBm maximum output power and -123 dBm sensitivity at 1,2 Kbps, with an IIP3 of 12 dBm. Current consumption is 9,3 mA in receive mode, 28 mA when transmitting at +13 dBm and 100 nA in sleep mode. The SX1235 operates from a 1,8 to 3,7 V supply.
Typical applications include building alarm systems, medical equipment and healthcare monitoring systems.
