RF6525

3.0V TO 4.2V, 2.4GHz FRONT END MODULE

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.
