Microsemi Corp. has released what it describes as an ultra low-power (ULP) RF transceiver with an extended temperature operating range of -40°C to 85°C for short-range wireless sensor products used in industrial applications. The ZL70251 can be used in unlicensed frequency bands ranging from 779-965MHz, which broadens the scope of operation from the previously supported North American (915MHz) and Europe (868MHz) bands to include China’s 779-787MHz radio frequency spectrum, added the company.

The ZL70251 is fully functional over the industrial temperature range, while still delivering the industry’s lowest peak power at 2mA in both transmit and receive mode, continued Microsemi. This performance enables extremely low-power wireless nodes to operate in harsh environments. It is offered in a compact 3 x 2mm chip scale package (CSP) and requires only two external components, which makes it ideal for products with space constraints, the firm noted.

A suite of ZL70251 product development support tools are available, including an application development kit (ADK), a low-power wireless communication software code starter for point-to-point connections and wireless sensor reference designs based on coin cell batteries.

The device is sampling now and will reach full production status in July 2013.
