Employ FM LNA for embedded antenna in portable apps

Music has become increasingly popular in recent years as a mobile value proposition. Transferring MP3 from the PC and playing on the mobile is now common, eased by decline in memory prices. This trend has re-ignited interest in FM radio on mobile as people want to keep up with the news, listen to new music, in addition to playing their MP3 collection.

NXP's FM LNAs can enable FM Radio on mobile phone speaker. They amplify the weak signal solving impedance mismatch between embedded antennas and the FM Radio receiver.

The FM LNA application circuit is built with BGU7003W (LNA MMIC). It needs 8 (9 components used in the EVB) external components for matching, biasing and decoupling. The layout has also additional foot print for 0402 components, those are reserved for different applications or ESD protection and matching purpose.
