ACFM-7102
PCS/Cellular/S-GPS Quintplexer
Data Sheet Description
Features
The Avago Technologies’ ACFM-7102 is a quintplexer that combines PCS and Cellular duplexer functions with a GPS filter. This device simplifies handset applications that are designed for simultaneous voice service and GPS positioning.
• Single Antenna connection for PCS duplexer, Cellular duplexer, and GPS filter • Miniature size – 5 x 8 mm footprint – 1.2 mm Max height • High Power Rating – +33 dBm Max Tx Power • Lead-Free Construction
The ACFM-7102 is designed with Avago Technologies’ Film Bulk Acoustic Resonator (FBAR) technology. The ACFM-7102 also utilizes Avago Technologies’ innovative Microcap bonded-wafer, chip scale packaging technology. This process allows the filters to be assembled in a module that is less than 1.2 mm high with a footprint of only 5 mm x 8 mm. Low Tx Insertion Loss reduces power amplifier current, extending battery life and talk time. The ACFM-7102 enhances receiver sensi-tivity and dynamic range with low Rx Insertion Loss and high rejection of Tx signals at the Rx ports. The excellent power handling capability of Avago Technologies’ FBAR bulk-mode resonators supports the high Tx output power levels needed in handsets while adding virtually no distortion.

Notes: 1) TC is the case temperature and is defined as the temperature of the underside of the quintplexer 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 arithmetic mean value of the parameter over its indicated frequency range at the specified temperature. Typical values may vary over time.

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 quintplexer where it makes contact with the circuit board.
Characterization A test circuit similar to that shown in Figure 1 was used to measure device performance. This circuit is designed to interface with Air Coplanar (ACP), Ground-SignalGround (GSG) RF probes of the type commonly used to test semiconductor wafers.
Short lengths of 50-ohm microstripline connect the DUT to ACP probe patterns on the board. A test circuit with an ACFM-7102 mounted in place is shown in Figure 2. S-parameters are measured using a vector network analyzer and calibrated ACP probe set.
The test circuit is a 17 x 14 mm PCB with a well-grounded pad to which the device under test (DUT) is soldermounted.
Phase data for s-parameters measured with ACP probe circuits are adjusted to place the reference plane at the edge of the quintplexer package.

Figure 40. Recommended PCB Land Print.
A PCB layout implementing design features similar to Figure 40 is recommended to optimize performance of the ACFM-7102. It is particularly important to maximize isolation between the Tx connections to the duplexer and the Rx ports. High isolation is achieved by (1) maintaining a continuous ground plane around the duplexer mounting area, (2) surrounding the I/O ports with sufficient ground vias to enclose the connections in a “Faraday cage”, and (3) preferably routing the Tx traces in a different metal layer than the Rx traces.
12
The latter is especially useful, not only to maintain TxRx isolation of the duplexer, but also to prevent leakage of the Tx signals into other components that could result in the creation of intermodulation products and degradation of overall system performance.
