Overview
The AD8348ARUZ-REEL7, produced by Analog Devices Inc., is a broadband quadrature demodulator designed for high-performance communications receivers. This integrated circuit combines an intermediate frequency (IF) amplifier, a variable gain amplifier (VGA), and baseband amplifiers, enabling direct quadrature demodulation from IF to baseband frequencies. The device is packaged in a 28-lead Thin Shrink Small Outline Package (TSSOP) and operates over a temperature range of -40°C to +85°C.
