NXP Semiconductors recently added the OL2385 family sub-GHz wireless transceivers to its low-power microcontroller and 2.4 GHz portfolio for Internet of Things (IoT) applications. Based on a PIN-to-PIN compatible, sub-GHz transceiver hardware platform, the OL2385 supports multiple wireless protocols (e.g., Sigfox, W-MBus powered by Xemex, and ZigBee IEEE 802.15.4).
With a two-way RF channel and common modulation schemes for networking applicatios, the OL2385 transceivers cover a wide range of frequency bands from 160 to 960 MHz. In addition, extended range radio operation is enabled with high sensitivity up to –128 dBm. Operation in congested environments is enhanced with 60 dB at 1 MHz of blocking performance and 60 dB of image rejection.
Platform features include: 14-dBm Tx output power compliant with ETSI limits; typical 29-mA transmit power consumption at full output power; less than 11 mA receive power consumption; excellent phase noise of –127 dBc at 1 MHz in the 868- and 915-MHz band for flexibility with external power amplifiers; and Japanese ARIB T108 standard compliant.
The OL2385 platform samples and development boards with SIGFOX are currently available. Mass production of preprogrammed parts are scheduled for the end of Q4 2017.
