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 3dB. This FEM meets or exceeds the system requirements for WiFi and ZigBee 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.
