Fujitsu Semiconductor Wireless Products Inc. has announced its next-generation, single-chip 2G/3G/4G transceiver ICs. The MB86L11A supports all modes including LTE (FDD and TDD), HSPA+, WCDMA, GSM, EDGE, EDGE-EVO, CDMA and TD-SCDMA.

The multimode, multiband transceiver improves benchmark performance for current drain and RF parameters, noted the company. The device features enhanced power control, envelope tracking (ET) and antenna tuning (AT), added Fujitsu. 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.


The MB86L11A supports LTE, HSPA+, WCDMA, EDGE, etc.

An advanced programming interface (API) feature minimizes factory calibration time, provides flexible port mapping and adds customized key performance indicator (KPI) features. The MB86L11A is built using the SAW-less architecture that eliminates the need for external LNAs.

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(SM) 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 supports mobile networks up to 20MHz. Sampling of the MB86L11A will begin in 2Q12.
