ACMD-7402
Miniature PCS Band Duplexer
Data Sheet
Description
The Avago ACMD-7402 is a miniature duplexer designed
for US PCS handsets.
The ACMD-7402 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.
Features
• Miniature size
- 3.8 x 3.8 mm footprint size
- 1.3 mm max height
• High power rating size
- +33 dBm max Tx power
• Lead-free construction
The ACMD-7402 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.
The ACMD-7402 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.
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.
Specifications
• Performance guaranteed –30 to +85°C
• Rx band performance (1930.5 – 1989.5 mHz) size
- Insertion loss: 3.8 dB max size
- Noise blocking: 43 dB min
• Tx band performance (1850.5 – 1909.5 mHz) size
- Insertion loss: 3.5 dB max size
- Interferer blocking: 52 dB min
Applications
• Handsets or data terminals operating in the US
PCS frequency band
The excellent power handling capability of the FBAR
bulk-mode resonators supports the high output power
levels needed in PCS handsets while adding virtually no
distortion.
