Fujitsu Semiconductor Asia has introduced the MB86L11A, the next-generation, single-chip 2G/3G/4G transceiver.
The MB86L11A is a multiband, multimode device that supports all modes, including LTE (FDD and TDD), HSPA+, WCDMA, GSM, EDGE, EDGE-EVO, CDMA, and TD-SCDMA.
It also supports benchmark performance for current drain and RF parameters.
The transceiver is built using the SAW-less architecture pioneered by Fujitsu, which also eliminates the need for external low noise amplifiers (LNAs) and supports all global FDD and TDD bands, including 1-21, 23-25, and 33-41.
The multimode, multiband transceiver includes different features in a smaller package with enhanced power control, envelope tracking (ET) and antenna tuning (AT).
Envelope tracking technology helps to lower the radio system power consumption, while improving transmitter efficiency. Antenna tuning optimises the total radiated power output from the antenna.
MB86L11A includes eight RF outputs on the transmitter, nine primary RF inputs and six diversity RF inputs on the IC.
The transceiver uses an open standard MIPI DigRFSM 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.
Fujitsu Semiconductor Asia associate vice-president Andy Chang said the new device augments Fujitsu’s family of state-of-the-art multimode, multiband single-chip transceivers, which are available in production quantities.
