The Fujitsu MB86L10A builds on the success of the MB86L01A, which was the first transceiver to eliminate external LNAs and inter-stage SAW filters from the TX and RX paths. The MB86L10A adds support for 4G, while reducing the package size to 6.5mm × 9.0mm.

A high-level programming model controls the radio using an open standard digital interface (3G and 4G DigRF/MIPI), which is compatible with a wide range of industry basebands.

Simultaneous support of both 3G and 4G interfaces allows the MB86L10A to be paired with one or two baseband processor ICs as needed.

Building on the revolutionary short-cycle RF programming method used in Fujitsu’s MB86L01A, the MB86L10A speeds RF subsystem implementations with simplified layerone programming and embedded intelligence. With this revolutionary approach, an engineer enters a single command stating the desired channel and power level. This command sets the parameters and times the events so that system compliance is virtually assured.

Eight outputs directly drive the power amplifier and eliminate the need for TX inter-stage SAW filters. The new RF front-end eliminates the need for LNAs and RX inter-stage SAW filters. Nine primary and five secondary inputs support LTE, WCDMA and GSM/EDGE. The receiver also incorporates anti-aliasing filters, digital channel filters, digital gain control and highdynamic-range ADCs.

The transceiver offers SPI and/or GPOs to control PAs, switching regulators and the antenna switch. A microcontroller unit in the transceiver enables simplified timing and control.

The compact module enables cell-phone manufacturers to reduce component count, board space and bill of materials.
