Fujitsu Microelectronics Now Shipping Industry’s First 3G SAW-less Transceiver: a New Multimode, Multiband UMTS/ GPRS/EDGE Solution

Compact module provides complete single-chip solution with an open standard digital interface for 3G/2G multimode phones

Fujitsu Microelectronics America, Inc. (FMA) has entered the mobile phone RF transceiver market with commercial production of a new highly integrated transceiver module supporting 3GPP WCDMA/EGPRS wireless phones.

The MB86L01A is the industry’s first multi-mode transceiver to eliminate 3G TX and RX inter-stage SAW filters and low-noise amplifiers (LNAs). The transceiver features a high-level programming model for controlling the radio using an open standard digital interface (3G DigRF/ MIPI), which is compatible with a wide range of industry basebands. The MB86L01A is available in volume shipments now.

The compact new transceiver module enables cell phone manufacturers to reduce component count, board space and bill of materials. The simplified programming model helps significantly reduce development time and simplify integration of the RF in a radio platform. The transceiver is optimized for compressed mode operation, and features quad‐band GSM/EDGE and up to four WCDMA bands in a single-phone configuration.

The transceiver includes six outputs that drive the power amplifier directly, so there is no need for SAW filters. The receiver provides seven inputs that support WCDMA and GSM/EDGE, and uses the new RF front‐end to eliminate the requirement for LNAs and SAW filters. The receiver also incorporates anti-aliasing filters, digital channel filters, digital gain control and high dynamic range ADCs.

The MB86L01A supports GSM bands (GSM850, EGSM900, DCS1800, PCS1900), WCDMA (Bands I, II, III, IV, V, VI, VIII, IX, X, and XI) and WCDMA HSDPA category 10 and HSUPA category 6. The transceiver includes a 3G DigRF interface to the baseband IC. It offers either SPI and/or GPOs to control PAs, switching regulators and antenna switch, with simplified timing and control enabled by a microcontroller unit in the transceiver.

The development of the MB86L01A transceiver module was enabled in part by the April acquisition by Fujitsu Microelectronics Limited of licenses and rights to the technology and intellectual property related to Freescale’s RF transceiver products for cellular handsets, and by Fujitsu’s acquisition of an RF team from Freescale Semiconductor in Tempe, Arizona. More than 130 of those design engineers are working on RF transceiver IC design, architecture, validation, verification, and reference designs. The group is also working on the next generation of products with engineering samples already available on a multimode WCDMA/EGPRS/LTE transceiver with a 4G DigRF interface.

“The MB86L01A transceiver is the first production-ready multimode RF transceiver to eliminate LNAs and 3G TX and RX SAWs, thus reducing component count, cost and board area,” said Vivek Bhan, senior director, RF Engineering for Fujitsu Microelectronics America. “This RF transceiver supports most global band configurations and its RF API slashes radio integration time. The result is smaller radios with faster time to market for handset manufacturers worldwide.”

“Fujitsu is entering the mobile phone RF transceiver market with a strong product designed to reduce development time, cost, and overall effort, while supporting a wide range of basebands,” said Fred Nakanishi, president of the ASSP Business Unit at Fujitsu Microelectronics Limited. “Fujitsu is committed to providing the leading-edge RF transceiver solutions to our customers worldwide, along with other semiconductor devices such as power management ICs, to optimize the customers’ competitive advantages.”


Production samples of the MB86L01A manufactured in 90nm CMOS process technology are available now in 142-pin 7.1 mm x 5.9 mm x 1mm LGA packages. Volume pricing is available upon request.
