Next Generation Qualcomm® RF360 Front End Solution
QFE33xx CMOS PA, QFE10xx Antenna Switch, and QFE25xx Antenna Tuner simplify LTE-A RF complexity.
The introduction of LTE-Advanced has opened up faster, more reliable options for carriers worldwide. But it has also added a whole
new layer of complexity. The next generation RF360 front end solution comprising power efficient CMOS power amplifliers and
antenna switches (QFE33xx/QFE10xx) and enhanced antenna tuner (QFE25xx) is designed to flexibly address the requirements of
regional and global CA band combinations. Building on the success of our current RF360 front end products, the next generation
RF front end solution is developed to simplify the multiband demands of LTE-A, now and moving forward. The new RF360 front
end products are expected to be available in commercial devices in the second half of 2014.
Addressing LTE-A.
Flexible solution for regional and global CA combinations.*
Utilizing up to three bands simultaneously dramatically increases data rates
and reduces latency. Yet these new combinations of CA bands create their
own challenges. Designed to handle up to three LTE bands simultaneously
in carrier aggregation mode, the combination of next generation CMOS PA
and antenna switch (QFE33xx/QFE10xx) delivers the flexibility needed for
even the most complex RF band configurations required by LTE-A.

Qualcomm RF front end solution
continues to simplify the LTE-A
RF front end. Higher performance, power and area efficient
PA and antenna switches
(QFE33xx/QFE10xx) are
designed to handle more than
twice as many bands
and band combinations as the
current generation products.
Wafer-level packaging further
reduces the overall PCB
footprint, opening more space
for other components.
