ADI Announces 5G Transceiver Chipset

News

Wideband 24 to 44GHz chipset supports stringent modulation schemes such as 1024QAM

Analog Devices has announced the ADMV1013 and ADMV1014, a paired integrated microwave upconverter and downconverter, respectively.

These SiGe chips operate over a wide frequency range with 50 Ω-match from 24 GHz up to 44 GHz, facilitating ease of design and reducing the costs of building a single platform that can cover all 5G mmWave frequency bands including 28 GHz and 39 GHz, says ADI.

Additionally, the chipset is capable of flat 1 GHz RF instantaneous bandwidth supporting all broadband services as well as other ultra-wide bandwidth transceiver applications.

Each upconverter and downconverter is highly integrated, comprising I (in-phase) and Q (quadrature-phase) mixers with on-chip programmable quadrature phase-shifter configurable for direct conversion to/from baseband (operable from DC to 6 GHz) or to an IF (operable from 800 MHz to 6 GHz).

Also included on-chip are voltage variable attenuators, transmit PA driver (in the upconverter) and a receive LNA (in the downconverter), LO buffers with x4 frequency multiplier and programmable tracking filters. Most programmability functions are controlled via an SPI serial interface. Through this port, these chips also provide a unique capability for each upconverter and downconverter to correct its respective quadrature phase imbalance, hence the usually difficult to suppress sideband emission can be improved from a typical value of 32 dBc, by 10 dB or more.

The chips are suited for the microwave radio platforms that operate in the emerging 28 GHz and 39 GHz 5G wireless infrastructure bands. The converters' 1GHz bandwidth capability, along with the upconverter's OIP3 of more than 20 dBm that supports stringent modulation schemes such as 1024QAM, are necessary to enable multi-Gigabit wireless data. Moreover, the chipset benefits other applications such as satellite and earth station broadband communication links, aircraft radios, RF test equipment and radar systems. Their superb linearity and image rejection performance are particularly compelling for improved range of microwave transceivers.

The ADMV1013 is offered in a 40-pin, 6mm x 6mm LGA, and the ADMV1014 is in a 32-pin, 5mm x 5mm LGA package. Samples and production quantities are available immediately.



CS International 26-27 March 2019, Sheraton Airport Hotel, Brussels

In its ninth year, CS International will continue to provide timely, comprehensive coverage of every important sector within the compound semiconductor industry. Presentations are split into 5 key themes and each industry key theme will be delivered by a keynote presentation from a leading industry figure as well as a market analyst presentation tailored to the theme. Together, the talks will detail breakthroughs in device technology; offer insights into the current status and the evolution of compound semiconductor devices; and provide details of advances in tools and processes that will help to drive up fab yields and throughputs. Attendees at the two-day conference will gain an up-to-date overview of the status of the CS industry, and have opportunities to meet many other key players within this community.

Places will be limited, so register your place today: https://cs-international.net
