RFMD RF6525 ZigBee前端解决方案
RFMD 公司的RF6525是2.4GHz 到2.5GHz频段的ZigBee前端模块(FEM),在发送(TX)通路集成功率放大器和谐波滤波器,接收通路(RX)集成了带旁路模式的LNA.此外,在TX和RX还集成了多种开关,并提供平衡输入和输出信号.TX输出功率22dBm,TX增益28dB,RX增益11.5dB,噪音为2.5dB. RF6525可用作基于ZigBee® 802.15.4系统的遥控和监视以及ISM频段的其它应用.本文介绍RF6525主要特性,功能方框图以及RF6525/EM357参考设计电路图与材料清单.
The RF6525 integrates a complete solution in a single Front End Module (FEM) for ZigBee® applications in the 2.4GHz to 2.5GHz band. This FEM integrates the PA plus harmonic filter in the transmit path and the LNA with bypass mode in the receive side. It also integrates a diversity switch and provides balanced input and output signals for both the TX and RX paths respectively.
The RF6525 FEM is ideal for ZigBee® systems operating with a minimum output power of 20dBm and high efficiency requirements. On the receive path, the RX Chain provides 11.5dB of typical gain with only 7mA of current and excellent NF of 2.5dB. This FEM meets or exceeds the system requirements for ZigBee® applications operating in the 2.4GHz to 2.5GHz band.
