Fujitsu unveils multimode, multiband transceiver IC for 2G/3G/4G mobile products

By Telecom Lead Team: Fujitsu Semiconductor Wireless
Products has launched MB86L11A, a single-chip transceiver 2G/3G/4G mobile

The multiband, multimode device supports all modes,
including LTE (FDD and TDD), HSPA+, WCDMA, GSM, EDGE, EDGE-EVO, CDMA, and
TD-SCDMA. Sampling of the MB86L11A will begin in Q2 2012.

“Fujitsu’s transceivers solve major challenges for
wireless device manufacturers planning to introduce both regional and global
devices with roaming capabilities in almost any combination of bands and
modes,” said Vivek Bhan, vice president, Fujitsu Semiconductor Wireless

The addition of the MB86L11A 2G/3G/4G transceiver,
following the success of the MB86L10A and MB86L12A, enhances the Fujitsu family
of transceivers with the compact design and latest features required by device

The MB86L11A 2G/3G/4G multimode, multiband transceiver
supports benchmark performance for current drain and RF parameters. The
transceiver includes many innovative features in a smaller package with
enhanced power control, envelope tracking and antenna tuning.

Envelope tracking technology helps to significantly lower
the radio system power consumption, while improving transmitter efficiency.
Antenna tuning optimizes the total radiated power output from the antenna. Both
features optimize the battery life of mobile devices.

An advanced programming interface feature minimizes
factory calibration time, provides flexible port mapping and adds customized
key performance indicator features. The MB86L11A is built using the SAW-less
architecture pioneered by Fujitsu, which also eliminates the need for external
low noise amplifiers.

Other features of the MB86L11A include eight RF outputs
on the transmitter, nine primary RF inputs and six diversity RF inputs on the
IC, giving greater flexibility to map ports and bands for different market
requirements. The transceiver uses an open standard MIPI DigRF interface to the
baseband, and has both DigRF 4G and DigRF 3G interfaces to work with existing
2G/3G baseband platforms as well as with newer multimode 4G basebands.

The device supports all global FDD and TDD bands,
including 1-21, 23-25, and 33-41. The MB86L11A, like earlier Fujitsu LTE
multimode, multiband transceivers, supports 2G/3G/4G networks up to 20MHz
bandwidth. Future transceivers on the roadmap include a 4G LTE optimized device
and a 3GPP Release 10, carrier-aggregation-compliant, single RFIC solution.
