Semtech Corporation announced the SX1233, a programmable ISM-band transceiver that combines the world's highest bit rate (600 kbps) with a world-class link budget (137 dB), ultra-low power consumption, excellent ACR (adjacent channel rejection) and blocking immunity. This combination of features provides high-bandwidth, radio link reliability, RF robustness and strong interference immunity. These are needed for long-range wireless video and imaging applications in home and building automation systems, smart meter readers, sensors, alarms, security systems, wireless monitoring and remote data measurement networks. The SX1233 offers high receive (RX) sensitivity to enhance reception of weaker signals, as well as a high transmitter (TX) output power programmable in 1 dB steps. High RX sensitivity and high TX output power equate to reliable transmission over greater distances and cost savings compared to traditional radio systems which require RF repeaters. Strong blocking immunity of 80dB and high linearity give the SX1233 transceiver "bullet-proof" front-end protection from both in-band and out-of-band interference (including cellular and devices sharing the 2.4 GHz band), enabling the device to meet stringent RX robustness requirements.
