Product Description
The RF5540 is designed specifically for high-performance WiFi applications in the
5GHz ISM band. This module integrates the LNA with bypass and an 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 RF5540 is provided in a 2mmx2mmx0.5mm, 12-pin QFN
package. This LNA + Switch front-end solution meets or exceeds the specification
requirements of IEEE 802.11a RF systems.
