Fujitsu Microelectronics America(FMA)has entered the mobile phone RF transceiver market with the launch of integrated transceiver module that supports 3GPP WCDMA/EGPRS wireless phones. It features a high-level programming model for controlling the radio using an open standard digital interface (3G DigRF/ MIPI).
According to Fujitsu, the new transceiver module enables cell phone manufacturers to reduce component count, board space,bill of materials,development time and simplify integration of RF in a radio platform. In addition, it also features squad-band GSM/EDGE, and up to four WCDMA bands in a single phone configuration..
The company said that the new module has six outputs to drive the power amplifier directly, in order to avoid SAW filters. It also provides seven inputs which will support WCDMA and GSM/EDGE. It includes a 3G DigRF interface to the baseband IC and offers either SPI or GPOs to control PAs, switching regulators and antenna switch, with simplified timing and control enabled by a micro controller unit in the transceiver.
Vivek Bhan, senior director of RF Engineering at Fujitsu Microelectronics America, said: “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. 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.”
