RF6545

3.0V TO 3.6V, 2.4GHz FRONT END MODULE

The RF6545 integrates a complete solution in a single Front End Module (FEM) for

the PA plus harmonic filter in the transmit path. It provides a single balanced TDD

access for Rx and Tx paths along with two ports on the output for connecting a

diversity solution or a test port. The device is provided in a 3.5mm x 3.5mm x

0.5mm, 20 pin QFN package.
