This device operates in the 315/433/470/868/915MHz license-free ISM bands and includes a fully integrated high power programmable amplifier, a frequency synthesizer and a digital demodulation function, etc., greatly simplifying the overall circuit design. With regards to standards, the device RF characteristics are compliant with ETSI/FCC specifications.

The device has an operating voltage ranging from 1.9V to 3.6V and a programmable transmitting power up to +13dBm. Its receiving sensitivity can be up to -120dBm at a data rate of 2kbps. It has a receiving current as low as 4.2mA at 433MHz and a transmission rate of up to 250kbps. The device also includes an ATR (Auto-Transmit-Receive) function.

The BC3602 includes an SPI control interface and meets with the industrial specification operating temperature of -40°C~85°C. It is supplied in a small 24-pin QFN (3mm×3mm) package type which will meet the requirements of low profile wireless product and module designs.
