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.
