Avago Technologies has released its fourth PCS duplexer based on film bulk acoustic resonator (FBAR) technology. Avago's ACMD-7403 offers best-in-class transmitter insertion loss to minimize power consumption and superior receiver insertion loss for excellent receiver sensitivity, according to the maker. Nearly 40% smaller than previous-generation products, the new PCS duplexer is designed for CDMA and UMTS mobile phone, data card, modem and femtocell applications.

It offers 2.7-dB maximum Tx band insertion loss, which lowers power consumption. A 3.2-dB maximum Rx band insertion loss achieves excellent receiver sensitivity. Additionally, the ACMD-7403 enhances the sensitivity and dynamic range of CDMA and UMTS receivers by providing more than 52-dB attenuation of the transmitted signal at the receiver input and more than 44-dB rejection of transmit-generated noise in the receive band.

The PCS duplexer size has been cut from 3.8 mm squared to 3.0 x 3.0 x 1 .2 mm, and provides maximum design flexibility with no compromise in electrical performance, said Avago. It also achieves a high power rating of +33 dBm absolute maximum Tx power and is RoHS-compliant.
