Employ FM LNA for embedded antenna in portable apps
Keywords:LNA? FM? embedded Antenna?
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.
