Applications

  • US PCS band handsets
  • Wireless Data terminals General Description The ACPF-7003 is a high rejection full band transmit filter designed for US PCS handsets. Its performance rivals split- band surface acoustic wave (SAW) transmit filters. Since a single filter provides the rejection, no switches are required, saving board space and external components, eliminat- ing switch loss, and reducing programming complexity. Furthermore, with 25dB rejection at 1830 MHz, it is a true split band replacement. The ACPF-7003 FBAR transmit filter utilizes Avago Tech- nologies’ Microcap bonded-wafer chip scale packaging technology. This process allows the ultra small filters to be assembled into a Molded Chip on Board (MCOB) Module. In typical cellular phone architectures, the transmit filter fits between the driver amplifier and the power amplifier. This filter reduces the noise in the Rx band being ampli- fied by the transmit chain, enhancing receiver sensitivity. High rejection keeps unwanted signals out of the receive path. Avago Technologies’ thin-Film Bulk Acoustic Resonator (FBAR) technology makes possible high-Q filters at a frac- tion their usual size.

Absolute Maximum Ratings[2] Notes: 1. Temperature is defined at case TC, the temperature of the underside of the filter where it makes contact with the circuit board. 2. Specifications are guaranteed over the given temperature range. Operation in excess of any one of these conditions may result in permanent damage to the device.
