Smart Grid - ZigBee® HAN/Smart Energy

RFMD’s portfolio of single-chip integrated front end modules (FEMs) are developed for high-performance ZigBee® Home Area Network(HAN) / Smart Energy applications in the 2.4 GHz to 2.5 GHz ISM band. The RF6525, RF6515, and RF6535 are specifically designed to operate with the Ember EM300 Series System-on-Chips (SoCs) - EM351 and EM357, EM250 SoC, and EM260 co-processor. The FEMs address the need for aggressive size reduction in an IEEE 802.15.4 front end design and offer a reduced footprint and minimized component count.

Features Applications
• Integrated PA, TX harmonic filtering, LNA, and switches
• High power up to >200 mW
• High gain 28 to 31 dB
