Avago Technologies has unveiled two ultrasmall W-CDMA duplexers that it says offers industry-best performance levels. Using new and improved film bulk acoustic resonator (FBAR) technology, Avago's miniaturized ACMD-7602/ACMD-7612 duplexers deliver optimal transmit and receive insertion loss for UMTS band 1 handsets, femtocells and data terminals.

Optimized for the UMTS Band 1 frequency band, Avago's FBAR-based ACMD-7602/ACMD-7612 improves talk time and handset sensitivity in a miniature 3mm x 2.5mm x 1.2mm max package. The duplexer offers a typical 1.1dB insertion loss in the Tx band to minimize current drain from the power amplifier, industry-best receiver sensitivity and dynamic range support with typical Rx band insertion loss of 1.1dB, interference blocking exceeding 53dB, and over 43dB of noise rejection. ACMD-7612 is similar to the ACMD-7602 and ships in the same ultrasmall package with best-in-class performance levels.

The performance and size advantages of Avago's duplexers make it well suited for several market applications, such as UMTS handsets and femtocells. UMTS is a global standard for 3G mobile communication systems designed for high data rate applications. UMTS Band 1 networks have already been deployed in both Europe and Asia. Femtocells act as small cellular base stations for the home or office that enable wireless providers to improve coverage and provide new services, such as IPTV.

Avago's ACMD-7602 and ACMD-7612 are available now. Pricing for the duplexer begins at 80 cents in high volumes.
