Radio Circuits to be Downsized Makers plan to downsize a single-chip keitai by substantially miniaturizing radio circuits, because batteries and motherboards will get to a point where there's little room for more downsizing. The miniaturization of radio circuits will proceed step by step to realize single-chip keitai, from the current stage of a single board to a single package to the single chip. There are three trends in the minituarization: (1) reduction of parts, (2) improvement of integration, and (3) reduction of packaging space. As for reduction of parts, direct conversion, or a circuit design technology that takes no intermediate frequency circuits, is drawing attention. Analog Devices Inc. of the United States is mass-producing chipsets [Othello] for mobile phones that meet the GSM standard, while developing chipsets for mobile phones that meet IMT-2000 standards (the W-CDMA method) jointly with Mitsubishi Electric Corp. Analog Devices said the number of parts in the radio circuits will be reduced from about 150 to about 90, and the size will be slashed by 30-50 percent. As for improved integration, the next-generation SiGe bipolar process technology will pull the trend. It will reduce power consumption more than 50 percent compared to products based on the conventional silicon bipolar process technology. Although IBM Corp. has been the runaway leader in the market, U.S.-based Maxim Integrated Products Inc. and other companies are ramping up production using that technology nikkeibp.asiabiztech.com Jim
