SAN JOSE, Calif., and SINGAPORE,  August 10, 2010 - Avago Technologies (Nasdaq: AVGO), a leading supplier of analog interface components for communications, industrial and consumer applications, today announced the industry’s first 4G/LTE Band 7 duplexer1 to its growing line of high isolation, 2 x 2.5 mm Film Bulk Acoustic Resonator (FBAR) duplexers for mobile handsets and data terminals. This FBAR duplexer will allow manufacturers to build handsets for the emerging 4G/LTE standard that are optimized for quality of voice service and battery life.

The ACMD-6007’s low 2.1 dB maximum insertion loss in the transmit channel minimizes current drain from the power amplifier and therefore extends handset battery life and talk time. The very low 2.5 dB receive channel insertion loss improves receiver sensitivity and dynamic range for better signal quality and an improved user experience. 

Handset receiver sensitivity and dynamic range is improved by the ACMD-6007 as it attenuates the transmit channel by 50 dB minimum in the receive channel, reducing transmit-generated noise in the receive band. This eliminates the need for interstage filters, making the handset less costly and freeing space that can be used for additional features.

The miniature ACMD-6007 is designed for LTE Band 7 (2500-2570 MHz uplink, 2620-2690 MHz downlink). Avago’s proprietary FBAR filter and patented Microcap wafer level silicon packaging technology produces an air mounted resonator with very high Q for sharp, low-loss filtering. The excellent 33 dBm transmit power handling capability of the ACMD-6007 supports the high output power levels used in mobile communications applications while adding virtually no distortion. Avago’s bulk filter structure is much better at handling the transmit power levels found in handsets than SAW (surface acoustic wave) technology based filters, especially in the higher frequency bands.

Note

1. A duplexer uses sharply tuned filters to isolate a transmitter from a receiver. This allows both to operate on the same antenna at the same time.
