Low cost ZigBee/IEEE802.15.4 reference design eliminate antenna, RF balun

Jennic has introduced a ZigBee- and IEEE 802.15.4-node reference design for its JN5139 wireless microcontroller. The design reduces the bill of materials (BOM) cost of modules for wireless sensor networks to under $5. This includes the cost of the JN5139 wireless microcontroller, a PCB antenna design, and all other ancillary components.
