Analog Devices Inc. ADRV9029 Quad RF Transceivers
Analog Devices Inc. ADRV9029 Quad RF Transceivers feature 4 differential transmitters, 4 differential receivers, integrated synthesizers, and digital signal processing functions. The transmitters include dedicated observation receiver inputs for monitoring each transmitter channel and use a direct conversion modulator for low noise operation with low power consumption. These devices also include two wide bandwidth, time shared, observation path receivers with two inputs each for monitoring transmitter outputs. The receiver subsystem consists of four independent, wide bandwidth, direct conversion receivers with a wide dynamic range. The complete transceiver subsystem includes automatic and manual attenuation control, DC offset correction, Quadrature Error Correction (QEC), and digital filtering.
The ADRV9029 transceivers include five fully integrated Phase-Locked Loops (PLLs) to achieve a high level of RF performance. These transceivers contain a fully integrated and low-power digital predistortion adaptation engine for use in power amplifier linearization. The ADRV9029 transceivers are powered directly from 1.0 V, 1.3 V, and 1.8 V regulators and are controlled via a standard serial peripheral interface serial port. Typical applications include 3G/4G/5G TDD and FDD massive MIMO, macro, and small cell base stations.
