DESCRIPTION
The Avago Low Insertion Loss in the Tx channel minimizes current drain from the power amplifier, while low Rx channel Insertion Loss improves receiver sensitivity. The Tx-Ant path of the ACMD-6013 provides at least 20 dB (24 dB Typ) rejection in the Public Safety Band. The duplexer utilizes Avago Technologies innovative temperaturecompensated FBAR technology, dramatically reducing the guard frequency required to transition from pass-band to stop-band. The ACMD-6013 is designed with Avago Technologies’ innovative 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 FBAR bulk-mode resonators supports the high output power levels used in mobile communications applications, while adding virtually no distortion. The ACMD-6013 also utilizes Avago Technologies’ advanced Microcap bonded-wafer, chip scale packaging technology. This process allows the filters to be assembled into a molded chip-on-board module with an overall size of only 2.0 x 2.5 mm and maximum height of 0.95 mm.
