    • Input and Output Matched to 50 ohm
    • Integrated 5 GHz Rejection Filter
    • 1.6 x 1.6 mm DFN Package

    The RFFM4227 is a low noise amplifier (LNA) designed for Wi-Fi 802.11b/g/n systems. The integrated input and output 50 ohm match minimizes layout area in the customer’s application, reduces the bill of materials and manufacturability cost. Performance is focused on a balance of low noise and gain that increases the receive sensitivity.

    The RFFM4227 integrates a bypass path that enables a defined gain step. The device is provided in a 1.6mm x 1.6mm x 0.5mm, 6-pin DFN package.
