ACPF-7001 High Rejection Tx Filter for US PCS Band Data Sheet Description This product is a high rejection full band transmit filter designed for US PCS handsets. Its performance rivals splitband surface acoustic wave (SAW) transmit filters. Since the rejection is provided by a single filter, no switches are required, saving board space and external components, eliminating switch loss, and reducing programming complexity. 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 amplified by the transmit chain, enhancing receiver sensitivity. High rejection keeps unwanted signals out of the receive path. Avago’s thin-Film Bulk Acoustic Resonator (FBAR) technology makes possible high-Q filters at a fraction of their usual size.

Furthermore, the inside of the filter (center pad Pin 9) is ground-plane; therefore it must be soldered to PCB ground. In summary: • Pins 1, 2, 3, 5, 6, 7, 9 are grounded. (Figure 6) • Demo board uses 10 mil top, 18 mil bottom Greek Coplanar Waveguide Over Ground plane (CPWG) style board. (See board layer Figure 6, 7) Note: For best performance, try to reproduce this board stack up closely. The demoboard uses CPWG transmission lines for high isolation between two ports. It uses via holes to connect the CPWG line from the underside of the board to the filter mounting pads on top. If Ground-SignalGround (GSG) type board is used, better return loss can be achieved since it eliminates connector mismatch. Figure 6.
