Analog Devices Inc. ADRV9002 Dual Narrow/Wideband RF Transceiver
Analog Devices Inc. ADRV9002 Dual Narrow/Wideband RF Transceiver is highly integrated and offers dual-channel transmitters, dual-channel receivers, integrated synthesizers, and digital signal processing functions. The IC delivers a versatile combination of high performance and low power consumption required by battery-powered radio equipment and can operate in both FDD and TDD modes. The ADRV9002 operates from 30MHz to 6000MHz and covers the UHF, VHF, licensed and unlicensed cellular bands, and industrial, scientific, and medical (ISM) bands. The IC can support both narrowband and wideband standards up to 40MHz bandwidth on both receive and transmit.
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, and programmable digital filters, which eliminate the need for these functions in the digital baseband. Several auxiliary functions such as auxiliary analog-to-digital converters (ADCs), auxiliary digital-to-analog converters (DACs), and general-purpose input/outputs (GPIOs) are integrated to provide additional monitoring and control capability. The transceiver also includes low power sleep and monitor modes to save power and extend the battery life of portable devices while monitoring communication.
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. Optimized for both narrowband and wideband signals, the fully integrated low power digital pre-distortion (DPD) enables the linearization of high-efficiency power amplifiers. All voltage controlled oscillator (VCO) and loop filter components are integrated to minimize the external component count. The local oscillators (LOs) have flexible configuration options and include fast lock modes.
The Analog Devices ADRV9002 core can be powered directly from 1.0V, 1.3V, and 1.8V regulators and is controlled via a standard 4-wire serial port. Other voltage supplies are used to provide proper digital interface levels and to optimize receiver, transmitter, and auxiliary converter performance. High data rate and low data rate interfaces are supported using configurable complementary metal-oxide semiconductors (CMOS) or low voltage differential signaling (LVDS) serial synchronous interfaces (SSI). The ADRV9002 is packaged in a 12mm x 12mm, 196-ball chip-scale package ball grid array (CSP_BGA).
