The ADRV9008-2 is a highly integrated, RF transmitter sub-system that is tunable over a range of 75 MHz to 6 GHz. The IC has a bandwidth of 450 MHz and consists of integrated dual channel transmitters, an observation path receiver, integrated synthesizers, and digital signal processing functions.
When in 3G/4G mode, it has a maximum large-signal bandwidth of 200 MHz. In multicarrier global system for mobile communications (MC-GSM) mode, which has higher in-band SFDR, the maximum large-signal bandwidth is 75 MHz. It can be powered directly from 1.3 V and 1.8 V regulators and is controlled via a standard 4 wire serial port. The high-speed JESD204B interface supports up to 12.288 Gbps lane rates. The ADRV9008-2 is available in a 12 x 12 mm, 196-ball chip scale ball grid array package and is ideal for 3G/4G/5G TDD macro cell base stations, TDD active antenna systems, Massive MIMO and Electronic Warfare applications.
The fully integrated phase locked loops (PLLs) provide high performance, low power fractional-N RF frequency synthesis for the transmitter and receiver sections. An additional synthesizer is used to generate the clocks needed for the converters, digital circuits, and the serial interface.
