Overview
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 transmitgenerated 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.
