AFEM-7780 UMTS2100 4x7 Front-end Module (FEM)
Data Sheet
Description
The AFEM-7780 is a fully matched WCDMA Band1 FrondEnd Module (FEM) featuring the integration of Avago Technologies’ power amplifier and FBAR. The AFEM-7780 offers extended talk time and excellent linearity by using CoolPAM technology, which enhances efficiencies in low and medium power mode. Idle current is as low as 11mA. The FBAR (Film Bulk Acoustic Resonator) based duplexer provides low insertion loss and outstanding isolat.

The AFEM-7780 offers extended talk time and excellent linearity by using CoolPAM technology, which enhances efficiencies in low and medium power mode. Idle current is as low as 11mA. The FBAR (Film Bulk Acoustic Resonator) based duplexer provides low insertion loss and outstanding isolation, which improves efficiency and RX sensitivity. By using CoolPAM and FBAR technologies, AFEM-7780 shows best performance with smaller footprint.
