RF6535

3.0V to 4.2V, 2.4GHz Front End Module

The RF6535 integrates a complete solution in a single Front End Module (FEM) for

WiFi and ZigBee® applications in the 2.4GHz to 2.5GHz band. This FEM integrates

the PA plus harmonic filter in the transmit path and an LNA 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 RF6535 FEM is ideal for ZigBee® systems operating with a minimum output

power of 20dBm and high efficiency requirements. On the receive path, the LNA

provides 11.5dB of typical gain with only 8mA of current and excellent NF down to

applications 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.
