FBAR duplexer shrinks by two-thirds
The ACMD-7401 is billed as the industry's smallest film bulk acoustic resonator (FBAR) duplexer for handsets, data cards and other wireless products operating in the US PCS frequency band.
Product award for duplexer and filter
The ACMD-7401 FBAR duplexer and ACPF-7002 full-band transmit filter from Agilent Technologies have been named as the 2004 Product of the Year by AnalogZone.
Duplexers play a critical role in CDMA handsets and data cards.
They separate incoming communications from outgoing communications to allow for simultaneous, two-way voice or data transmission.
In a CDMA handset, the full-band transmit filter is incorporated between the driver amplifier and the power amplifier to reduce noise in the receive band, thereby enhancing receiver sensitivity.
"The tremendous acceptance of our FBAR filter components has fueled a new generation of thinner, smaller CDMA flip phones", said Bryan Ingram, Vice President and General Manager of the Wireless Semiconductor Division in Agilent's Semiconductor Products Group.
"The significant size and performance advantage has made these components an industry standard with more than 80% share of the US PCS handset market".
"Agilent has also integrated the duplexer with its E-pHEMT power amplifiers and detectors to create miniature RF front-end modules, enabling manufacturers to further increase battery life and offer more features".
Agilent continues to exploit its innovative FBAR technology by further reducing the size and increasing the performance of its second-generation duplexers and transmit filters.
The Agilent ACMD-7401 is the industry's smallest FBAR duplexer.
Built with Agilent's innovative Microcap bonded-wafer, chip-scale packaging, it is less than one-tenth the volume of competing ceramic devices (1.4mm high with a 5.0 x 5.0mm footprint).
The Agilent ACPF-7002 is the industry's smallest full-band transmit filter (1.0mm high with a 1.6 x 2.0mm footprint).
It eliminates the need for a second filter, a radio-frequency switch and associated passive components.
This reduces the printed circuit board area required for the transmit filter by up to 90%, while lowering manufacturing costs and eliminating the need for interface design and programming. Request free introductory details about products from Avago Technologies ...
