Avago Technologies Announces Industry's Smallest Duplexers for U.S. PCS and UMTS Band I Mobile Phones

Avago announced two FBAR (film bulk acoustic resonator) duplexers for handsets, PC data cards and other wireless products operating in the U.S. PCS and UMTS frequency bands.

FBAR Duplexers' Miniature Height/Footprint, High Performance Surpass SAW and Ceramic Duplexers to Improve Talk Time and Handset Sensitivity

Avago Technologies has announced two new FBAR (film bulk acoustic resonator) duplexers for handsets, PC data cards and other wireless products operating in the U.S. PCS (personal communications service) and UMTS (Universal Mobile Telecommunications System) frequency bands.

Avago's FBAR technology offers significantly smaller size and higher performance compared to competitive SAW (surface acoustic wave) and ceramic duplexers. The new FBAR duplexers achieve their miniature size through Avago's innovative Microcap bonded-wafer chip scale packaging.

This size advantage allows handset manufacturers to produce ultra-slim phones, while incorporating the advanced multimedia features that today's users desire. Duplexers play a critical role in CDMA and W-CDMA (wideband code division multiple access) mobile phones and data cards by separating incoming communications from outgoing communications to allow for simultaneous two-way voice or data transmission.
