Analog Devices ADRV9022 Product Info

The ADRV9022 is a highly integrated, RF agile transceiver that offers four independently controlled transmitters and receivers, dedicated observation receiver inputs for monitoring each transmitter channel, integrated synthesizers, and digital signal processing that delivers a complete transceiver solution. This device meets the performance needs of cellular infrastructure, including small cells, macro 3G/4G/5G systems, and massive, multiple in and multiple out (MIMO) base stations.

The receiver subsystem consists of four wide bandwidth, direct conversion receivers with excellent dynamic range. The transmitters use direct conversion modulation, enabling low noise operation and power efficiency. Two wide bandwidth, time shared observation receivers with dual inputs monitor the transmitter outputs.

The transceiver integrates automatic and manual attenuation control, DC offset correction, quadrature error correction (QEC), and digital filtering, removing the need for these in the digital baseband. Additional integrated functions include analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and general-purpose inputs and outputs (GPIOs) for flexible digital control.

To ensure high RF performance, the device includes five fully integrated phase-locked loops (PLLs). Two for high-performance, low power, fractional-N RF synthesizers, one for an independent local oscillator (LO) mode for the observation receiver, one for the converter and digital circuits, and one for the serial interface clock.
