With cell phone makers ready to transition to the Long-Term Evolution (LTE) standard later this year, designers require advanced transceiver technology that supports a broad range of industry basebands including 2G and 3G, in addition to LTE. Designers also need an efficient, compact, highly integrated transceiver to reduce total component count, board space and BOM.
The Fujitsu MB86L10A transceiver meets those requirements. Designed for multimode, multiband LTE, UMTS and EDGE mobile handsets, the transceiver eliminates external LNAs and inter-stage SAW filters from the TX and RX paths of 3G and LTE lineups. The MB86L10A incorporates anti-aliasing filters, digital channel filters, digital gain control and high-dynamic-range ADCs. A proprietary high-level programming model can control the radio using the 3G and 4G DigRF/MIPI interfaces, supporting a broad range of industry basebands.
Because the MB86L10A supports 3G and 4G interfaces, it can be paired with one or two baseband processor ICs. The MB86L10A supports GSM (GSM850, EGSM900, DCS1800, PCS1900), W-CDMA (bands I, II, III, IV, V, VI, VIII, IX, X and XI) and LTE (FDD bands 1, 3, 4, 6, 7, 8, 9, 10, 11, 13, 17 and TDD bands 38 or 40).
The MB86L10A builds on the short-cycle RF programming method developed for Fujitsu's MB86L01A RF transceiver. The programming capability enables the MB86L10A to speed RF subsystem implementations with simplified layer-one programming and embedded intelligence. An MCU core unit simplifies timing and control. SPI and/or GPOs control PAs, switching regulators and the antenna switch.
The transceiver can be used in mobile phones and Internet devices, data cards and embedded modules. It comes in a compact 6.5 × 9.0 × 1.0 mm LGA package. For details, visit www.fujitsu.com/downloads/MICRO/fma/pdf/RFTrans_MB86L10A.pdf.
