ADI's ADRV9008/ADRV9009 are highly integrated, radio frequency (RF), agile dual receivers and dual transceivers offering integrated synthesizers and digital signal processing functions. These ICs deliver a versatile combination of the high performance and low power consumption demanded by 3G and 4G macro cell TDD base station applications.

The receiver consists of two independent, wide bandwidth (BW), direct conversion receivers with state-of-the-art dynamic range. The complete receive subsystem includes automatic and manual attenuation control, dc offset correction, quadrature error correction (QEC), and digital filtering, eliminating the need for these functions in the digital baseband. RF front-end control and several auxiliary functions such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and general-purpose input/outputs (GPIOs) for the power amplifier (PA) are also integrated.

The transmitters (ADRV9009) use an innovative direct conversion modulator that achieves high modulation accuracy with exceptionally low noise. The observation path consists of a wide bandwidth direct-conversion receiver with state-of-the-art dynamic range. The transmitters use an innovative direct conversion modulator that achieves high modulation accuracy with exceptionally low noise.

The core of the ADRV9008/AERV9009 can be powered directly from 1.3 V and 1.8 V regulators and is controlled via a standard 4-wire serial port. Comprehensive power-down modes are included to minimize power consumption during normal use. The ADRV9008/ADRV9009 is packaged in a 12 mm x 12 mm, 196-ball chip-scale ball grid array (CSP_BGA).
