WiFi Front End Module: RFFM4203Source: RFMD
This 3.0V to 5.0V Front End Module (FEM) operates in the 2.4 GHz to 2.5 GHz (ISM band) frequency range and is ideal for IEEE802.11b/g/n WiFi applications, portable battery-powered equipment, WiFi access points, gateways, and set top boxes.
The RFFM4203 Front-End-Module (FEM) features an ultra-small form factor (3mm x 3mm x 1.0mm, 16-pin package) and integrating matching, resulting in fewer external components and a smaller layout area. This FEM integrates a 2.4GHz to 2.5GHz Power Amplifier (PA), Low Noise Amplifier (LNA) with bypass mode, power detector coupler for improved accuracy, and some filtering for harmonic rejection. Additional information can be found on the available datasheet.
