At the European Microwave Week in Munich, Germany, this week, Avago Technologies unwrapped two ultra-small, WCDMA duplexers with new levels of performance. Using new and improved film bulk acoustic resonator (FBAR) technology, Avago's miniaturized ACMD-7602/ACMD-7612 duplexers deliver best-in-class transmit and receive insertion loss for UMTS band 1 handsets, femtocells, and data terminals, claimed Avago.

Optimized for the UMTS band 1 frequency, the FBAR-based ACMD-7602/ACMD-7612 improves talk time and handset sensitivity in a miniature 3.0 x 2.5 x 1.2 mm (max) package. The new duplexer offers a typical 1.1 dB 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 1.1 dB, interference blocking exceeding 53 dB, and over 43 dB of noise rejection. ACMD-7612 is the mirror image of the ACMD-7602 and ships in the same ultra-small package with best-in-class performance levels.

Designed for UMTS handsets and femtocells, the ACMD-7602 and ACMD-7612 are available now. Pricing for the duplexer begins at $0.80 in high volumes.
