Product Summary
The AD8348ARUZ is a Quadrature Demodulator with an integrated intermediate frequency (IF) variable-gain amplifier (VGA) and integrated baseband amplifiers. The AD8348ARUZ is suitable for use in communications receivers, performing quadrature demodulation from IF directly to baseband frequencies. The baseband amplifiers have been designed to directly interface with dual channel A-to-D converters such as the AD9201, AD9283, and AD9218 for digitizing and post- processing. The applications of the AD8348ARUZ include QAM/QPSK Demodulator, W-CDMA/CDMA/GSM/NADC, Wireless Local Loop, and LMDS/MMDS.
