Agilent HPMD-7904 FBAR Duplexer for US PCS Band Data Sheet Features * Miniature size: less than 2 mm high; 5.6 x 11.9 footprint General Description The HPMD-7904 is a miniaturized duplexer designed for US PCS handset, designed using Agilent Technologies' Film Bulk Acoustic Resonator (FBAR) Technology. The HPMD-7904 features a very small size: it is less than 2 mm thick and has a footprint of only 5.6 x 11.9 mm2. The HPMD-7904 enhances the sensitivity and dynamic range of CDMA receivers, providing more than 50 dB attenuation of transmitted signal at the receiver input, and more than 40 dB rejection of the transmitgenerated noise in the receive band. Typical insertion loss in the Tx channel is only 1.8 dB, minimizing current drain from the power amplifier. Typical insertion loss in the Rx channel is 2.2 dB, improving receiver sensitivity. Agilent's thin-Film Bulk Acoustic Resonator (FBAR) technology makes possible high-Q filters at a fraction their usual size. The excellent power handling of the bulk-mode resonators supports the high output powers needed in PCS handsets, with virtually no added distortion. * Rx Band: 1930-1990 MHz Typical performance: Rx noise blocking: 42dB Insertion loss: 2.2 dB typical 3.0 dB band edge Board Diagram * Tx Band: 1850-1910 MHz Typical performance: Tx interferer blocking: 54dB Insertion Loss: 1.8 dB typical 2.5 dB band edge Functional Block Diagram Tx /4 1 Ant 3 port numbers are circled * 30 dBm Tx power handling Rx 2 Applications * Handsets or data terminals operating in the US PCS frequency band HPMD-7904 Electrical Specifications, ZO = 50, TC[1] as indicated Symbol Parameters Units +25C[1,3] Min Typ Max fRX Receive Bandwidth MHz 1930.6 -- 1989.4 1930.6 -- 1989.4 1930.6 -- 1989.4 S23 Rx Attenuation in Transmit Band (1850.6 - 1909.4 MHz) dB 50 54 -- 50 52 -- 50 52 -- S23 Rx Typical Insertion Loss in Receive Band (1935-1985MHz) dB -- 2.2 3.5 -- 2.2 3.8 -- 2.2 3.8 S23 Rx Insertion Loss at Edges of Receive Band (1930.6-1935 MHz and 1985-1989.4 MHZ) dB -- 3.0 3.5 -- 3.0 3.8 -- 3.0 4.5 S23 Ripple in Receive Band dB -- 1.5 -- -- 1.5 -- -- 2.0 -- S22 Rx Return Loss in Receive Band dB 8.0 10 -- 8.0 10 -- 8.0 10 -- fTX Transmit Bandwidth MHz 1850.6 -- 1909.4 1850.6 -- 1909.4 1850.6 -- 1909.4 S31 Tx Attenuation in Receive Band (1930.6 - 1935 MHz) dB 40 42 -- 40 42 -- 37 42 -- S31 Tx Attenuation in Receive Band (1935- 1989.4 MHz) dB 40 42 -- 40 42 -- 40 42 -- S31 Tx Insertion Loss in Transmit Band (1855- 1905 MHz) dB -- 1.8 3.0 -- 1.8 3.5 -- 1.8 3.5 S31 Tx Insertion Loss at Edges of Transmit Band (1850.6-1855 MHz and 1905-1909.4 MHz) dB -- 2.5 3.0 -- 3.0 3.8 -- 3.0 3.6 S31 Ripple in Transmit Band dB -- 2.0 -- -- 3.0 -- -- 2.0 -- S11 Tx Return Loss in Transmit Band dB 8.0 10 -- 8.0 10 -- 8.0 10 -- S33 Ant Return Loss, Tx and Rx bands dB 8.0 -- -- -- -- -- -- -- -- S21 Tx-Rx Isolation, 1850.6 - 1909.4 MHz (Transmit Band) dB 50 54 -- 50 54 -- 50 54 -- S21 Tx-Rx Isolation, 1930.6 - 1935 MHz (Receive Band) dB 40 42 -- 40 42 -- 38 42 -- S21 Tx-Rx Isolation, 1935- 1989.4 MHz (Receive Band) dB 40 42 -- 40 42 -- 40 42 -- Absolute Maximum Ratings[4] Parameter Unit Value Operating temperature[1] C -30 to +85 Storage temperature[1] C -30 to +100 Notes: 1. TC is defined as case temperature, the temperature of the underside of the duplexer where it makes contact with the circuit board. 2. Specifications are given at operating temperature limits and room temperature. To estimate performance at some intermediate temperature, use linear interpolation. 3. Specifications are guaranteed over the given temperature range, with the input power to the Tx port equal to +30 dBm (or lower) over all Tx frequencies. The application of input power levels in excess of +30 dBm will not destroy the duplexer, but its performance may exceed the specification limits given above. 4. Operation in excess of any one of these conditions may result in permanent damage to the device. 2 +85C[1,2,3] Min Typ Max -30C[1,2,3] Min Typ Max The plots below provide typical performance obtained from samples of the HPMD-7904 duplexer.

Device Orientation. Solder Recommendations The HPMD-7904 FBAR duplexer (and its variants) is an assembly consisting of two LCC ceramic packages, containing the Tx and Rx filters, mounted to a small circuit board. Both packages on the circuit board are mounted in place using Sn96.5/Ag3.5 solder (shaded in Table 1). The recommended solder profile for the FBAR duplexer is shown in Figure 16. Guidelines and a typical profile are both shown. This typical profile was tested on ten samples of the duplexer, each of which was subjected to the profile six times without effect upon the mechanical or electrical characteristics of the device. Solder temperatures and times in excess of those given in the guidelines of Table 1 may result in damage to the duplexer or changes in its characteristics. Table 1.
