The ADRV9029 from Analog Devices is a Quad RF Transceiver that operates from 75 to 6000 MHz. It has four independently controlled transmitters, dedicated observation receiver inputs for monitoring each transmitter channel, four independently controlled receivers, integrated synthesizers, and digital signal processing functions providing a complete transceiver solution. It provides the performance demanded by cellular infrastructure applications, such as small cell base station radios, macro 3G/4G/5G systems, and massive multiple in/multiple out (MIMO) base stations.
The transceiver has 4 differential transmitters, 4 differential receivers and 2 observation receivers with 2 inputs each for monitoring transmitter outputs. It has an integrated DPD adaptation engine for power amplifier linearization, a crest factor reduction engine, independent fractional-N radio frequency synthesizers and clock synthesizers. This transceiver requires a DC supply of 1/1.3/1.8 V and consumes under 6.86 W of power. It can be controlled via SPI, GPIO and 24.33 Gbps JESD204B/JESD204C digital interfaces.
The ADRV9029 supports TDD and FDD applications and multichip phase synchronization for all local oscillators and baseband clocks. It also includes five fully integrated phase-locked loops (PLLs). Two PLLs provide low noise and low power fractional-N RF synthesis for the transmitter and receiver signal paths. A third fully integrated PLL supports an independent local oscillator (LO) mode for the observation receiver. The fourth PLL generates the clocks needed for the converters and digital circuits, and a fifth PLL provides the clock for the serial data interface.
The ADRV9029 is available in a 289-ball chip scale ball grid array (CSP_BGA) package that measures 14 × 14 mm and is ideal for 3G/4G/5G TDD and FDD massive MIMO, macro and small cell base stations applications.
