The RF6525 front-end module (FEM) meets or exceeds the system requirements of ZigBee applications operating in the 2.4 to 2.5-GHz frequency band and supports multiple applications, including smart energy/advanced metering infrastructure (AMI), home area network (HAN), wireless ZigBee home automation, portable battery-powered equipment, and general 2.4-GHz ISM band systems. The part integrates a 20-dBm PA with a Tx harmonic output filter in the transmit path, and a LNA with bypass mode in the receive path.
It includes a low-insertion-loss, high-isolation, double-pole double-throw (DPDT) diversity transfer switch and a two-port 50-Ω Rx/Tx integrated balun that simplifies matching and provides balanced input and output signals for both the Tx and Rx paths. In the receive path, the Rx chain provides 11.5 dB of typical gain with only 7 mA of current and a noise figure of 2.5 dB. ($1.69 ea/10,000 — available now.)
