ACPF-7003

ACPF-7003 High Rx and Image Rejection Tx Filter for US PCS Band Data Sheet General Description 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. 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. Features • High rejection from a single filter with no switches required • 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. Electrical Specifications, Zo=50 Ω +25° C Symbol f IL IL IL D S21 S21 S21 S21 S21 S21 S21 S21 S11, S22 Pin max Parameters Passband [1850.6 - 1909.4] Insertion Loss 1850.6-1855 MHz Insertion Loss 1855-1905 MHz Insertion Loss 1905-1909.4 MHz Ripple, 1850-1910 MHz Min Rejection, 1930.6-1990 MHz Min Rejection 10 -1715 MHz Min Rejection 1715 - 1785 MHz Min Rejection 1785 - 1830 MHz Min Rejection 1990 - 2500 MHz Min Rejection 2500 - 3820 MHz Min Rejection 3820 - 5730 MHz In-band return loss Safe Input Power Level Units MHz dB dB dB dB dB dB dB dB dB dB dB dB dBm 35 25 25 25 30 22 15 10 20 13 45 2.0 1.5 2.5 3.5 2.5 3.0 2.5 35 25 25 25 30 22 15 10 20 13 45 3.5 2.5 3.0 Min Typ Max Min -30° to +85° C Typ Max Absolute Maximum Ratings[2] Parameter Operating temperature[1] Storage temperature[1] Unit °C °C Value -30 to +85 -40 to +125 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.  Typical Performance (25 C, Zo = 50 Ohms) Figure 1. Attenuation (dB) vs. frequency Figure 2.

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.
