ACMD-7401

The ACMD-7401 is a miniaturized duplexer designed using Agilent's Film Bulk Acoustic Resonator (FBAR) technology. The ACMD-7401 is the first duplexer built with Agilent's innovative Microcap bonded-wafer chip scale packaging technology. This process allows the ultra small filters to be assembled in a molded chip-on-board (MCOB) module that is less than 1.4 mm high with a 5 x 5 mm footprint.

The ACMD-7401 enhances the sensitivity and dynamic range of CDMA receivers, providing more than 50 dB attenuation of transmitted signal at the receiver input, and more than 40 dB rejection of the transmit-generated noise in the receive band. Typical insertion loss in the Tx channel is only 1.8 dB,minimizing current drain from the power amplifier. Typical insertion loss in the Rx channel is 2.2 dB,improving receiver sensitivity.

Agilent's thin-film Bulk Acoustic Resonator (FBAR) technology makes possible high-Q filters at a fraction their usual size. The excellent power handling of the bulk-mode resonators ACMD-7401 supports the high output powers needed in PCS handsets, with virtually no added distortion.
