ACPF-7003 High Rx and Image Rejection Tx Filter for US PCS Band Data Sheet General Description Features The ACPF-7003 is a high rejection full band transmit filter designed for US PCS handsets. Its performance rivals splitband surface acoustic wave (SAW) transmit filters. Since a single filter provides the rejection, no switches are required, saving board space and external components, eliminating switch loss, and reducing programming complexity. Furthermore, with 25dB rejection at 1830 MHz, it is a true split band replacement. • High rejection from a single filter with no switches required The ACPF-7003 FBAR transmit filter utilizes Avago Technologies’ 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. • True split band replacement • Passband: 1850-1910 MHz • 35 dB min Attenuation, 1930-1990 MHz • 2.5 dB Typical Insertion Loss • 25dB image rejection at 1830 MHz • Space saving solution - Small footprint: 1.6 x 2.0-mm solution - Low profile package: 0.9 mm high (Typ) - 1.0mm (Max) In typical cellular phone architectures, the transmit filter Applications fits between the driver amplifier and the power amplifier. This filter reduces the noise in the Rx band being ampli- • US PCS band handsets fied by the transmit chain, enhancing receiver sensitivity. • Wireless Data terminals 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 fraction their usual size.

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. Typical Performance (25 C, Zo = 50 Ohms) Figure 1. Attenuation (dB) vs. frequency Figure 3.

S(2,2) PCB Interface & Mounting instructions Demo boards Mounting Consideration and board description Demo boards are available for sampling. (See board drawing in Figures 7, 8, and 9.) The ACPF-7003 FBAR filter has one input (Pin 1), one output (Pin 3) and two grounds (Pins 2 and 4.) • Demo board uses 3 mil Getek Microstrip. The demo board uses CPWG transmission lines for high isolation between the two ports. It uses via holes to connect the CPWG line from the underside of the board to the filter mounting pads on top. Note: For best performance, try to reproduce this board stack up closely. If Ground-Signal-Ground (GSG) type board is used, better return loss can be achieved since it eliminates connector mismatch.
