Highly integrated transmitter IC reduces BOM

Keywords:IC transmitter? radio highly integrated? ISM-band Semtech?

Semtech Corp. is offering a high-performance integrated ISM-band transmitter IC dubbed SX1230 that integrates all the radio components on a CMOS die, minimizing the need for other passive components and reducing BOM by up to 40 percent.

Built using Semtech's TrueRF technology, the SX1230 features dual power amplifiers with 35dB programmable output power, ranging from -18dBm to +17dBm with a constant radio performance over the full power supply and temperature range. Semtech's TrueRF technology reduces phase noise so that the SX1230's performance is a full 10dB higher than competing devices with a signal purity that simplifies regulatory testing in both Europe (ETSI EN 300-220-1) and North America (FCC part 15.231,15.247 and 15.249), according to the company.

The SX1230 can operate in the 315-, 434-, 868- and 915MHz license-free ISM bands, and is power-optimized for low consumption, drawing as low as 8mA depending on output power level.

The SX1230 features programmable data rates up to 600Kbit/s. It supports both narrowband and wide-band modes for use in professional and consumer applications such as automatic meter reading, remote control and remote keyless entry. The flexible device operates in MCU mode where it acts as a SPI slave, or in standalone SPI master mode, with control and payload information coming from externally connected programmable ROM (EEPROM) device.

Pricing starts at $1.15 each in 3,000-piece lots. The SX1230 is available immediately in production quantities.
