Agilent ACPF-7001 High Rejection Tx Filter for US PCS Band Data Sheet Features • High rejection from a single filter with no switches required 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. Agilent’s thin-Film Bulk Acoustic Resonator (FBAR) technology makes possible high-Q filters at a fraction of their usual size. Package 1 3.0 ± 0.15 SQ 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. • Passband: 1850 –1910 MHz 33 dB min Attenuation, 1930 – 1990 MHz 3.5 dB max Insertion Loss 2 8 3 4 9 7 6 4: Input 8: Output 1, 2, 3, 5, 6, 7, 9: Grounded Center pad grounded See Figure 10 for details.

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.

Note: For best performance, try to reproduce this board stack up closely. For example, if customer’s ground layer is less than 14 mils, void the 1st ground layer (and others if necessary) and use the next available ground closest to 14 mils. If less than 14 mils dielectric is used, parasitic capacitance will slightly degrade the return loss and rejection. If Ground-SignalGround (GSG) type board is used, better return loss can be achieved since it eliminates connector mismatch. 14 mils Getek® Layer 2 (ground) Layer 3 is unused 2nd dielectric is for mechanical support only Getek® material (ML200D) dielectric constant: 4.2 Figure 6.
