AFE7071IRGZ – TEXAS INSTRUMENTS

The Analog Devices AFE7071IRGZ is a highly integrated, single-chip, 1.8GHz direct-conversion receiver designed for software-defined radio (SDR) applications. It features an integrated LNA with selectable gain stages (up to 30dB), a quadrature mixer, and a 14-bit ADC with a sampling rate of up to 1.8GSPS. The device operates from a 3.3V supply voltage and is housed in a 64-pin LQFP package. Its core functionality centers around wideband RF signal acquisition and digitization, suitable for applications requiring high dynamic range and low noise figure._x000D_

Key specifications include an input frequency range of 700MHz to 1800MHz, a typical noise figure of 4dB, and an integrated digital signal processor (DSP) for initial signal processing. The AFE7071IRGZ excels in scenarios demanding high-speed data acquisition and processing, such as advanced spectrum monitoring, wideband communications receivers, and software-defined radar systems. Its advantage lies in its single-chip integration, reducing external component count and PCB footprint, while maintaining high performance and low power consumption compared to discrete solutions. The integrated DSP offloads processing from the host processor, improving overall system efficiency.
