AD8348 Datasheet (Analog Devices) - 50-1000 MHz Quadrature Demodulator

AD8348, 50-1000 MHz Quadrature Demodulator

The AD8348 is a broadband quadrature demodulator with an integrated intermediate frequency (IF), variable gain amplifier (VGA), and integrated baseband amplifiers.

It is suitable for use in communications receivers, performing quadrature demodulation from IF directly to baseband frequencies.
