The F0453B from Renesas is an integrated dual-path RF front-end module that operates from 3.4 to 3.8 GHz. It consists of an RF switch and two low noise amplifier (LNA) stages in each path. This FEM can be used in the analog front-end receiver of an Active Antenna System (AAS).
The LNA of the RF front-end provides a gain of 34.5 dB with 6 dB of gain control, a noise figure of 1.35 dB, P1dB of 15 dBm and IP3 of 23 dBm. It has channel isolation of more than 40 dB and switch isolation of more than 50 dB.
The F0453B has a settling time of 31 ns, requires 3.3 volts of supply voltage and is matched to 50 ohms for ease of integration into the signal path. It is available in a 32-LGA package that measures 5 x 5 x 0.8 mm and is ideal for Multi-mode, Multi-carrier receivers, 4.5G (LTE Advanced), and 5G band 42 and 43 applications.
