Agilent Technologies Introduces Smaller FBAR Transmit Filter for U.S. PCS Band Mobile Phones, Data Cards.Business Editors/High-Tech Writers PALO ALTO, Calif.--(BUSINESS WIRE)--Jan. 26, 2004 Second-Generation Device Provides Higher Performance in 66 Percent Smaller Package Agilent Technologies Inc. (NYSE NYSE See: New York Stock Exchange :A) today announced a new, smaller film bulk acoustic resonator resonator /res·o·na·tor/ (rez´o-na?ter) 1. an instrument used to intensify sounds. 2. an electric circuit in which oscillations of a certain frequency are set up by oscillations of the same frequency in another (FBAR FBAR Film Bulk Acoustic Resonator FBAR Foreign Bank Account Report FBAR First Born Anal Retentive ) full-band transmit filter for handsets, data cards and other wireless products operating in the U.S. 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. (personal communications service "Our breakthrough packaging technology enables us to reduce the size of our FBAR transmit filter, creating a perfect complement to our smaller second-generation FBAR duplexer," said Bryan Ingram, vice president and general manager of Agilent's Wireless Semiconductor Division. "The combination significantly reduces board space, making it possible to design even slimmer, feature-rich mobile phones, and provide additional functionality in PC cards for laptop computers." In typical 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. handset architectures, the transmit filter is incorporated between the driver amplifier and the power amplifier to reduce noise in the receive band, thereby enhancing receiver sensitivity. The high rejection capability of Agilent's miniature FBAR transmit filter keeps out unwanted signals, and its low insertion loss increases transmitter efficiency and performance. Many of today's CDMA handset designs use two 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) split-band filters to cover the 1850-1880 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. and 1880-1910 MHz portions of the PCS transmit frequency range, with the appropriate filter selected via a radio-frequency switch. Agilent's FBAR full-band filter eliminates the need for a second filter, a radio-frequency switch and associated passive components. This space savings reduces the printed circuit board area required for the transmit filter by up to 90 percent, while lowering manufacturing costs and eliminating the need for interface design and programming. The ACPF-7002 is the first full-band transmit filter built with Agilent's innovative Microcap bonded-wafer chip scale packaging (hardware) Chip Scale Packaging - (CSP) A type of surface mount integrated circuit packaging that provides pre-speed-sorted, pre-tested and pre-packaged die without requiring special testing. An example is Motorola's Micro SMT packaging. technology. This process allows the ultra-small filter to be assembled in a molded-chip-on-board (MCOB MCOB Multi-Chip on Board (semiconductor technology) MCOB Marine Corps Opportunities Book (US DoD) ) module that is less than 1.0 mm high with a 1.6 mm x 2.0 mm footprint. ACPF-7002 Features In addition to small size and high performance, the ACPF-7002 offers these features for handset and data card design: -- typical insertion loss of 2.5 dB over the 1850-1910 MHz transmit band -- minimum attenuation Loss of signal power in a transmission. Attenuation The reduction in level of a transmitted quantity as a function of a parameter, usually distance. It is applied mainly to acoustic or electromagnetic waves and is expressed as the ratio of power densities. of 33 dB over the 1930-1990 MHz receive band -- receive chain with a lower third-order intercept point (less dynamic range), thus saving current -- filter specified over the -30 degrees C to +85 degrees C temperature range U.S. Pricing and Availability The ACPF-7002 is priced at $0.54 each in 100,000-piece quantities. Samples and production quantities are immediately available. Agilent plans to make the ACPF-7002 available through its distribution partners in the first half of 2004.
