PALO ALTO, Calif.--(BUSINESS WIRE)--Feb. 15, 2005--
Miniature Device Features Improved Performance in Receive Band
Agilent Technologies Inc. (NYSE:A) today announced a
higher-performance film bulk acoustic resonator (FBAR) full-band
transmit filter for handsets, data cards and other wireless products
operating in the U.S. PCS (personal communications service) frequency
band. Compared with full-band SAW (surface acoustic wave) transmit
filters offered by competitors, Agilent's FBAR filter provides
superior performance in an equivalent or smaller package.
The Agilent ACPF-7003 features higher rejection -- 35 dB minimum,
45 dB typical in the 1930-1990 MHz receive band -- than Agilent's
widely used ACPF-7002 full-band filter. It also offers lower maximum
insertion loss over portions of the 1850-1880 MHz transmit band and
improved input and output match to 50 ohms.
"Our improved FBAR transmit filter is an indication of Agilent's
commitment to offering industry-best products for mobile handsets,"
said Bryan Ingram, vice president and general manager of Agilent's
Wireless Semiconductor Division in Agilent's Semiconductor Products
Group. "We recently announced our 100th design win for these
industry-leading miniature filters, which is a testament to their
tremendous market acceptance."
In typical CDMA 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 CDMA handset designs use two SAW split-band filters to cover
the 1850-1880 MHz 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-7003 is built with Agilent's innovative Microcap
bonded-wafer chip scale packaging technology. This process allows the
ultra-small filter to be assembled in a molded-chip-on-board module
that is less than 1.0 mm high with a 1.6 mm x 2.0 mm footprint. The
filter is specified over the -30(degree)C to +85(degree)C operating
temperature range.
U.S. Pricing and Availability
The Agilent ACPF-7003 is priced at $0.55 each in 100,000-piece
quantities. Samples and production quantities are available now
through Agilent's direct sales channel and worldwide distribution
partners.
