Mitsubishi Electronics Offers Compact, Battery-Saving GaAs FET Amplifier for PCS Band CDMA Cellular Phone Applications; Low Idle Drain Current, Low Operating Voltage and Improved Power Efficiency Add to Life of Lithium-Ion Batteries.SUNNYVALE, Calif.--(BUSINESS WIRE)--Dec. 7, 1999-- Mitsubishi Electronics America's Electronic Device Group today announced the North American North American named after North America. North American blastomycosis see North American blastomycosis. North American cattle tick see boophilusannulatus. availability of a low-voltage, low-current, high-efficiency three-stage gallium arsenide (GaAs) field effect transistor See FET. (electronics) field effect transistor - (FET) A transistor with a region of donor material with two terminals called the "source" and the "drain", and an adjoining region of acceptor material between, called the "gate". (FET FET: see transistor. (Field Effect Transistor) One of two major categories of transistor; the other is bipolar. FETs use a gate element that, when charged, creates an electromagnetic field that changes the conductivity of a silicon ) RF amplifier module for PCS (1) (Personal Communications Services) Refers to wireless services that emerged after the U.S. government auctioned commercial licenses in 1994 and 1995. This radio spectrum in the 1. Band (1.85 - 1.91 GHz) CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. cellular phone applications. The amplifier, FA01384, features an extremely low idle drain current (Idq) of only 85 mA (typical), improved power efficiency to 37 percent, and a low 3.2-volt operating voltage that allows for 10 percent more conversation time in cellular phone applications. The module also has a compact 7.5 x 7.5 x 1.7 mm footprint. "This new amplifier is specifically targeted to extend the battery life of CDMA cellular phones while supplying all the power and features customers have come to expect, all within a compact footprint," said Bryon Gutow, product marketing manager for microwave/RF products at Mitsubishi Electronics America. "This amplifier's power saving design saves battery life whether the cellular phone is being used or is in idle mode." The amplifier also maintains 700 mW of output power with an excellent linearity of -29 dBc. The module is input/output matched at 50 ohms. Packaging, Availability and Pricing Mitsubishi's FA01384 GaAs FET RF amplifier module is available in a metal capped, glass-ceramic package. The device is now sampling and in volume production. Pricing is $7 each in 10,000-unit quantities. About Mitsubishi Electric and Mitsubishi Electronics America Mitsubishi Electric Corporation manufactures a diverse range of microwave and RF semiconductors for linear, low-noise and high-power communications applications, including satellite and terrestrial transmitters and receivers, marine and vehicular mobile radios, cellular phones and subscriber units. The company produces gallium arsenide (GaAs) FETs, MICs, MMICs and HEMTs; silicon RF power transistors and modules; and surface acoustic wave A surface acoustic wave (SAW) is an acoustic wave traveling along the surface of a material having some elasticity, with an amplitude that typically decays exponentially with the depth of the substrate. (SAW) filters for the industrial and consumer markets. Mitsubishi markets its microwave and RF semiconductors in North America through the Electronic Device Group of Mitsubishi Electronics America. Mitsubishi Electric Corporation and its North American affiliate, Mitsubishi Electronics America Inc., are world-class suppliers of semiconductors and electronic products for computers, communications, industrial, Internet-enabled, automotive, and visual applications. Mitsubishi combines its systems-level expertise and high-level silicon process technologies to provide chip, chipset and system-on-chip solutions. The company is ranked among the top-tier worldwide semiconductor suppliers and offers an extensive range of semiconductor and computer system components for the North American marketplace, including embedded DRAM/flash/SRAM, ASIC (Application Specific Integrated Circuit) Pronounced "a-sick." A chip that is custom designed for a specific application rather than a general-purpose chip such as a microprocessor. , ASSP (Application Specific Standard Part) An ASIC chip that is designed as a generic device for a particular market. Whereas an ASIC is typically used only by its creator, ASSPs are used by many different companies in the design of their products. See ASIC. , MCU (1) (MicroController Unit) A computer on a single chip. See microcontroller. (2) (Multipoint Control Unit) A device that is used to moderate a videoconference of three or more end points (users at computers or groups of users , discrete memory, graphics, microwave/RF, optoelectronic, storage, and flat-panel display products Additional information on the Mitsubishi Electric Semiconductor Group is available at http://www.mitsubishichips.com. |
