Chipmaker RFaxis Grows Product Offerings for IoT Market

RFaxis, a fabless semiconductor firm based in Irvine, Calif., has added three RF front-end integrated circuits to its family of RFeIC products for the sub-GHz and 2.4 GHz frequency bands. The RFX2403, RFX2413 and RFX1030 chips are targeted at the global IoT or machine-to-machine (M2M) market.

The RFX2403 includes transmit-receive switching circuitry required for devices compliant with the 802.15.4 ZigBee/Thread protocol, as well as proprietary ISM radios in the 2.4 GHz spectrum. The chip can also be used in devices that support the Bluetooth Low Energy (BLE) standard.

RFaxis says the RFX2413 is optimized for us in sub-GHz 802.15.14 and proprietary ISM radios, such as LoRa, Sigfox and Weightless, and Narrowband Cellular IoT (NB-CIoT) specifications. All three new products come with associated matching networks, RF decoupling and harmonic filters, in a single-die, single-chip, bulk CMOS device in miniature QFN packages measuring 3 millimeters by 3 millimeters (0.1 inch by 0.1 inch). According to the company, all three products are operable at an ambient temperature of up to 125 degrees Celsius (257 degrees Fahrenheit), which is required by most uses in LED lighting and in smart-home, -office and -building applications.

Samples of the new products will be available during this quarter, according to the company.

Gimbal, Couchbase, Partner for Beacon Apps

Database provider Couchbase and Bluetooth beacon manufacturer Gimbal have collaborated to develop a means by which Couchbase customers can create mobile applications that cache data on a consumer's phone, which can be useful when a consumer is in a location with poor cellular connectivity. For example, in a sports stadium, airport or festival space, the developer could establish a beacon-based geofence or configure specific beacons that would trigger cached content on consumers' phones to be used in a push notification to those consumers.
