ACMD-7409-BLK

ACMD-7409 Miniature PCS Band Duplexer Data Sheet Description Features The Avago ACMD-7409 is a miniature duplexer designed for US PCS handsets. • Miniature size – 3.8 x 3.8 mm footprint size – 1.3 mm max height The ACMD-7409 is designed with Avago Technologies’ Film Bulk Acoustic Resonator (FBAR) technology, which makes possible ultra-small, high-Q filters at a fraction of their usual size. The ACMD-7409 also utilizes Avago’s innovative Microcap bonded-wafer, chip scale packaging technology. This process allows the filters to be assembled in a molded chip-on-board module that is less than 1.3 mm high with a footprint of only 3.8 x 3.8 mm. • High power rating size – +33 dBm max Tx power • Environmental – RoHS Compliant – Halogen Free – TBBPA Free Specifications The ACMD-7409 enhances the sensitivity and dynamic range of PCS receivers by providing more than 54 dB attenuation of the transmitted signal at the receiver input and more than 45 dB rejection of transmit-generated noise in the receive band. • Performance guaranteed –30 to +85°C Maximum Insertion Loss in the Tx channel is only 3.5 dB, which minimizes current drain from the power amplifier. Insertion Loss in the Rx channel is 3.8 dB max, improving receiver sensitivity. • Tx band performance (1850.5 – 1909.5 mHz) size – Insertion loss: 3.5 dB max size – Interferer blocking: 52 dB min The excellent power handling capability of the FBAR bulkmode resonators supports the high output power levels needed in PCS handsets while adding virtually no distortion. The ACMD-7409 is an environmentally green version of the ACMD-7402 duplexer.

TC is the case temperature and is defined as the temperature of the underside of the Duplexer where it makes contact with the circuit board. 2. Min/Max specifications are guaranteed at the indicated temperature with the input power to the Tx ports equal to or less than +29 dBm over all Tx frequencies unless otherwise noted. 3. Typical data is the average value of the parameter over the indicated band at the specified temperature. Typical values may vary over time. Refer to “Characterization” section for measurement details. 4. At Tx input power between +26 dBm and +29 dBm, the Insertion Loss at the upper edge of the Tx band (1907– 1909.5 MHz) will be slightly degraded. From 1907 to 1909.5 MHz, the maximum Insertion Loss specification at Tc = +85°C is guaranteed to +26 dBm input power.  Absolute Maximum Ratings[1] Parameter Unit Value Storage Temperature °C –65 to +125 Maximum RF Input Power to Tx Ports dBm +33 Maximum Recommended Operating Conditions[2] Parameter Unit Value Operating Temperature, Tc[3], °C –40 to +100 Operating temperature, Tc[3], Tx Power 30 dBm °C –40 to +85 Tx Power 29 dBm Notes: 1. Operation in excess of any one of these conditions may result in permanent damage to the device. 2. The device will function over the recommended range without degradation in reliability or permanent change in performance, but is not guaranteed to meet electrical specifications. 3. TC is defined as case temperature, the temperature of the underside of the Duplexer where it makes contact with the circuit board. Characterization A test circuit similar to that shown in Figure 1 was used to measure typical device performance. This circuit is designed to interface with Air Coplanar (ACP), GroundSignal-Ground (GSG) RF probes of the type commonly used to test semiconductor wafers. The test circuit is a 7 x 7 mm PCB with a well-grounded pad to which the device under test (DUT) is solder-mounted. A test circuit with a ACMD-7409 mounted in place is shown in Figure 2. S-parameters are then measured using a network analyzer and calibrated ACP probe set. Phase data for s-parameters measured with ACP probe circuits are adjusted to place the reference plane at the edge of the Duplexer Short lengths of 50-ohm microstripline connect the DUT to the ACP probe patterns on the board.
