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.
