RFFM5541
4.9GHz to 5.85GHz Switch and LNA Front End Solution
The RFFM5541 is designed specifically for high-performance WiFi applications in the 5GHz ISM band. This module integrates the LNA with bypass and a SPDT switch of a Front End solution. The integrated input and output match reduces the number of external components keeping cost down and utilizing minimum layout area for implementation. The RFFM5541 is provided in a 2mm x 2mm x 0.5mm, 12-pin QFN package. This LNA + Switch front-end solution meets or exceeds the specification requirements of IEEE 802.11a RF systems.
