Agilent Technologies Announces Industry's First Front-End Module for U.S. PCS Mobile Phones.Business Editors/High-Tech Writers Wireless Systems Design Conference and Expo SAN DIEGO--(BUSINESS WIRE)--March 8, 2004 Two Industry-Best Technologies Combine to Improve Performance, Reduce Size and Cost of CDMA-1900 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. Handsets Agilent Technologies This article needs sources or references that appear in reliable, third-party publications.

(NYSE NYSE See: New York Stock Exchange :A) today announced the industry's first combined 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. duplexer/power amplifier front-end module (FEM FEM Female FEM Finite Element Method FEM Feminine FEM Finite Element Model FEM Fédération Européenne des Métallurgistes (European Metalworkers' Federation) FEM Faculdade de Engenharia Mecânica (Brasil) ) for use in dual-band and 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 This integration of two industry-best technologies enables manufacturers to produce smaller-size handsets with higher power-added efficiency, which means more functionality, extended battery life and longer phone talk-time. The FEM's miniature size also helps manufacturers trim costs via an up to 50 percent savings in board space, and an up to 65 percent reduction in parts count, including passive components.

For example, a circuit added to filter out unwanted frequencies may reduce the output current by some amount. See injection loss. and low temperature coefficient," said Bryan Ingram, vice president and general manager of Agilent's Wireless Semiconductor Division. "Our E-pHEMT power amps provide the industry's best power-added efficiency, enabling longer battery life and more talk time. The combination of these two innovative technologies in a compact 'by-band' RF front-end module gives our handset customers faster time to market, better performance through optimized impedance matching, and greater board-space savings to make room for additional handset features." Strong demand from handset manufacturers continues to fuel combined shipments of Agilent's E-pHEMT power amplifiers and FBAR duplexers at a rate of more than four million units per month. The Agilent AFEM-7731 announced today is a fully matched CDMA-1900 MHz FEM, integrating Agilent's highly efficient ACPM-7833 E-pHEMT (enhancement-mode pseudomorphic high electron mobility transistor) power amplifier with its miniature ACMD-7401 FBAR (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 ) duplexer and all matching circuitry into a compact 5 x 8 x 1.3 mm chip-on-board module. Compared to designs using separate power amplifiers and duplexers, the AFEM-7731 features higher effective power-added efficiency (PAE PAE Physical Address Extension Pae Pseudomonas aeruginosa PAE Power-Added Efficiency PAE Programa de Aperfeiçoamento de Ensino (Brazil) PAE Port Access Entity (IEEE 802. ) for longer talk time, and high isolation and low loss in the receive band for high sensitivity. The optimized matching between the power amplifier and duplexer eliminates the need for a bulky and costly isolator, which further reduces the cost and size of the handset. Mobile phone frequency bands and air interface standards differ by geography, so multiband, multimode handsets need a certain combination of frequency bands and standards to meet local radio requirements. Handset radio front-end architectures need to be flexible to work with these various combinations. "By-band" front-end modules that are partitioned by frequency band (for example, 1900 MHz and 850 MHz) can be used in any phone with a CDMA-1900 MHz PCS band. For example, Agilent's AFEM-7731 can be used in single-band and dual-band CDMA handsets, and in multi-air interface phones such as those with CDMA, W-CDMA See WCDMA. and GSM. Agilent is developing a variety of modules using this by-band approach. AFEM-7731 Features In addition to its small footprint and ultra-thin size, the AFEM-7731 RF FEM offers these features for handset and data card design: -- 3.4 V operation (3.2 V min.) -- High efficiency, with low current (380 mA typical current at 24.5 dBm linear output power) provides approx. 50 mA current savings -- Low quiescent current implemented using fixed and dynamic bias control -- High isolation (low Tx leakage at Rx port) Availability The AFEM-7731 is shipping in prototype quantities through Agilent's direct sales channel to select mobile phone manufacturers. Production volumes are expected by Q3 2004. Pricing at full product release is expected to be similar to the combination of separate Agilent ACPM-7833 (CDMA E-pHEMT power amplifier module) and ACMD-7401 (CDMA FBAR duplexer) devices. Agilent is also developing a cell-band CDMA 850 MHz RF front-end module, which it expects to ship in volume by Q4 2004.
