ACMD-7403
Description
The Avago Technologies’ ACMD-7403 is a miniature duplexer designed for use in UMTS Band II and PCS (Blocks A- F) handsets. The ACMD-7403 enhances the sensitivity and dynamic range of handset receivers by providing more than 54 d B attenuation of the transmitted signal at the receiver input and more than 44 d B rejection of transmit-generated noise in the receive band. Maximum Insertion Loss in the Tx channel is only 2.7 d B, which minimizes current drain from the power amplifier. Insertion Loss in the Rx channel is a maximum of 3.2 d B, thus improving receiver sensitivity. The ACMD-7403 is designed with Avago Technologies’ Film Bulk Acoustic Resonator (FBAR) technology, which makes possible ultra-small, high-Q filters at a fraction of their usual size. The excellent power handling capability of the FBAR bulk-mode resonators supports the high output power levels needed in PCS handsets while adding virtually no distortion. The ACMD-7403 also utilizes Avago Technologies’...
