ACMD-7403
Miniature UMTS Band II / PCS Duplexer
Data Sheet
Description
Features
The Avago Technologies’ ACMD-7403 is a miniature
duplexer designed for use in UMTS Band II and PCS
(Blocks A–F) handsets.
The ACMD-7403 enhances the sensitivity and dynamic
range of handset receivers by providing more than 54 dB
attenuation of the transmitted signal at the receiver input
and more than 44 dB rejection of transmit-generated
noise in the receive band.
• Miniature Size
• 3.0 x 3.0 mm Max footprint
• 1.2 mm Max height
• High Power Rating
• 33 dBm Abs Max Tx Power
• Lead-Free Construction
Maximum Insertion Loss in the Tx channel is only 2.7 dB,
which minimizes current drain from the power amplifier.
Insertion Loss in the Rx channel is a maximum of 3.2 dB,
thus improving receiver sensitivity.
Specifications
• Rx Band Performance, 1930.5-1989.5 MHz, – 30 to +85°C
• Rx Noise Blocking: 44 dB min
The ACMD-7403 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 capa-
bility of the FBAR bulk-mode resonators supports the
high output power levels needed in PCS handsets while
adding virtually no distortion.
The ACMD-7403 also utilizes Avago Technologies’ innova-
tive Microcap bonded-wafer, chip scale packaging tech-
nology. This process allows the filters to be assembled in
a molded chip-on-board module that is less than 1.2 mm
high with a footprint of only 3.0 mm x 3.0 mm.
• Insertion Loss: 3.2 dB max
• Tx Band Performance, 1850.5-1909.5 MHz, – 30 to +85°C
• Tx Interferer Blocking: 52 dB min
• Insertion Loss: 2.7 dB max
Applications
Handsets or data terminals operating in the PCS (A–F)
frequency band.
