Functional Block Diagram
Product Description
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® applica-
tions operating in the 2.4GHz to 2.5GHz band. The device is provided in a 3.5mm x
3.5mm x 0.5mm, 20-pin QFN package.
