ACMD-7612  
Miniature UMTS Band I Duplexer  
Data Sheet  
Description  
Features  
• Miniature size  
- 2.5 x 3.0 mm max footprint  
- 1.2 mm max height  
The Avago ACMD-7612 is a miniature duplexer designed  
for use in UMTS Band I handsets.  
Maximum Insertion Loss in the Tx channel is only 1.5 dB,  
which minimizes current drain from the power amplifier.  
Insertion Loss in the Rx channel is a maximum of 2.0 dB,  
improving receiver sensitivity.  
• High power rating  
- +33 dBm Abs Max Tx Power  
• Lead-free construction  
The ACMD-7612 enhances the sensitivity and dynamic  
range of WCDMA receivers by providing more than  
53 dB attenuation of the transmitted signal at the  
receiver input and more than 43 dB rejection of trans-  
mit-generated noise in the receive band.  
Specifications  
• Performance guaranteed –30 to +85°C  
• Rx band performance (2110 – 2170 mHz)  
- Insertion loss: 2.0 dB max  
- Noise blocking: 43 dB min  
The ACMD-7612 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 excellent power handling capabil-  
ity of the FBAR bulk-mode resonators supports the high  
output power levels needed in handsets while adding  
virtually no distortion.  
• Tx band performance (1920 – 1980 mHz)  
- Insertion loss: 1.5 dB max  
- Interferer blocking: 53 dB min  
Applications  
• Handsets or data terminals operating in the UMTS  
Band I frequency range  
The ACMD-7612 also utilizes Avago Technologies’ in-  
novative Microcap bonded-wafer, chip scale packaging  
technology. This process allows the filters to be assem-  
bled in a molded chip-on-board module that is less than  
1.2 mm high with a maximum footprint of only 2.5 mm  
x 3.0mm.

Figure 20. PCB layout  
A PCB layout implementing design principles similar to  
those illustrated in Figure 16 is recommended to optimize  
performance of the ACMD-7612.  
It is particularly important to maximize isolation between  
the Tx connection to the duplexer and the Rx port. 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 trace in a different metal  
layer than the Rx.  
The latter is especially useful, not only to maintain Tx-  
Rx isolation of the duplexer, but also to prevent leakage  
of the Tx signal into other components that could  
result in the creation of intermodulation products and  
degradation of overall system performance.
