Description
The Fujitsu MB86L10A is the industry’s first commercial multi-
mode transceiver to eliminate external LNAs and inter-stage SAW
filters from the TX and RX paths of both 3G and LTE lineups.
The transceiver features a high-level programming model for
controlling 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 layer-one
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 high-
dynamic-range ADCs. The new, compact transceiver module
enables cell-phone manufacturers to reduce component count,
board space and bill of materials.
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 MB86L10A supports GSM (GSM850, EGSM900, DCS1800,
PCS1900), WCDMA (bands I, II, III, IV, V, VI, VIII, IX, X, and
XI), LTE (FDD bands 1, 3, 4, 6, 7, 8, 9, 10, 11, 13, 17 and TDD
bands 38 or 40).
