AFEM-7780
UMTS2100 4x7 Front-end Module (FEM)
Data Sheet
Description
The AFEM-7780 is a fully matched WCDMA Band1 Frond-
End 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 isolation,
which improves efficiency and RX sensitivity.
By using CoolPAM and FBAR technologies, AFEM-7780
shows best performance with smaller footprint.
Feature

Handling and Storage
ESD (Electrostatic Discharge)
Electrostatic discharge occurs naturally in the environ-
ment. With the increase in voltage potential, the outlet of
neutralization or discharge will be sought. If the acquired
discharge route is through a semiconductor device, de-
structive damage will result.
ESD countermeasure methods should be developed and
used to control potential ESD damage during handling in
a factory environment at each manufacturing site.
MSL (Moisture Sensitivity Level)
Plastic encapsulated surface mount package is sensitive to
damage induced by absorbed moisture and temperature.
Avago Technologies follows JEDEC Standard J-STD 020B.
Each component and package type is classified for
moisture sensitivity by soaking a known dry package at
various temperatures and relative humidity, and times. Af-
ter soak, the components are subjected to three consecu-
tive simulated reflows.
The out of bag exposure time maximum limits are de-
termined by the classification test describe below which
corresponds to a MSL classification level 6 to 1 according
to the JEDEC standard IPC/JEDEC J-STD-020B and J-STD-
033.
AFEM-7780 is MSL3. Thus, according to the J-STD-033 p.11
the maximum Manufacturers Exposure Time (MET) for this
part is 168 hours. After this time period, the part would
need to be removed from the reel, de-taped and then
re-baked. MSL classification reflow temperature for the
AFEM-7780 is targeted at 260°C +0/-5°C. Figure and table
on following page shows typical SMT profile for maximum
temperature of 260 +0/-5°C.
