RFFM4227

Wi-Fi Low Noise Amplifier

General Description

The RFFM4227 is a low noise amplifier (LNA) designed

for Wi-Fi 802.11b/g/n systems. The integrated input and

output 50Ω 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.

6 Pad 1.6ꢀxꢀ1.6ꢀmm DFN Package

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.
