ADRV9002 Dual Narrowband and Wideband RF Transceiver

Analog Devices' ADRV9002 is a highly integrated RF transceiver with dual-channel transmitters, receivers, integrated synthesizers, and digital signal processing functions. It is a high-performance, highly linear, high-dynamic range transceiver designed to optimize performance vs. power consumption system. The device is configurable and ideally suited to demanding, low-power, portable, and battery-powered equipment. The ADRV9002 operates from 30 MHz to 6000 MHz. It covers the UHF, VHF, industrial, scientific, and medical (ISM) bands and cellular frequency bands in narrowband (kHz) and wideband operation up to 40 MHz. The ADRV9002 is capable of both TDD and FDD operation.

The transceiver consists of direct conversion signal paths with state-of-the-art noise figure and linearity. Each complete receiver and transmitter subsystem includes DC offset correction, quadrature error correction (QEC), and programmable digital filters, eliminating the need for these functions in the digital baseband. In addition, several auxiliary functions, such as auxiliary analog-to-digital converters (ADCs), auxiliary digital-to-analog converters (DACs), and general-purpose inputs/outputs (GPIOs), are integrated to provide additional monitoring and control capability.

The fully integrated phase-locked loops (PLLs) provide high performance, low power, fractional-N frequency synthesis for the transmitter, receiver, and clock sections. Careful design and layout techniques provide the isolation required in high-performance personal radio applications.
