Analog Devices debuts mmWave 5G chipset

Analog Devices (ADI) that combines ADI’s advanced beamformer IC, up/down frequency conversion (UDC), and additional mixed signal circuitry. This optimized “Beams to Bits” signal chain represents a unique set of capabilities only available from ADI.

The new mmWave 5G chipset includes the 16-channel ADMV4821 dual/single polarization beamformer IC, 16-channel ADMV4801 single-polarization beamformer IC and the ADMV1017 mmWave UDC. The 24- to 30-GHz beamforming + UDC solution forms a 3GPP 5G NR compliant mmWave front-end to address the n261, n257 and n258 bands. The high channel density, coupled with the ability to support both single- and dual-polarization deployments, greatly increases system flexibility and reconfigurability for multiple 5G use cases while best-in-class equivalent isotropically radiated power (EIRP) extends radio range and density.

“Millimeter-wave 5G is an emerging technology with great potential,” said Karim Hamed, general manager of Microwave Communications at Analog Devices. “It can be extremely difficult to design these systems from the ground up, balancing system-level challenges in performance, standards, and cost. This new solution leverages ADI’s best-in-class technology, long legacy in RF, microwave and mmWave communications infrastructure, and deep expertise across the RF spectrum to simplify the design process for customers, reduce overall component count, and accelerate the path to 5G deployment.”

Keysight submits 5G NR non-standalone RF test case

Keysight Technologies' 5G Conformance Toolset was first to submit 5G new radio (NR) non-standalone (NSA) radio frequency (RF) test cases for PTCRB validation approval in frequency range 2 (FR2), as well as for 5G NR standalone (SA) protocol test cases in frequency range 1 (FR1), accelerating market introduction of 5G NR mobile devices.

PTCRB is a certification forum consisting of leading U.S. mobile operators.

Keysight’s 5G Conformance Toolset continues to offer unique validation coverage for 5G NR standalone, which also plays an important role in accelerating 5G NR mobile device certification for commercial introductions around the world.

"By being first to submit 5G NR test cases for PTRCB validation approval, Keysight is enabling mobile operators to speed up their ability to deliver on the promise of 5G and capitalize on early commercial 5G NR deployments,” said Kailash Narayanan, vice president and general manager of Keysight's wireless test group. “We’re proud to once again showcase our 5G technology leadership position which was achieved as a result of our close collaborations with market makers, as well as our significant contributions to the 5G NR standards.”

Since the beginning of this year, Keysight has obtained initial GCF approval for validated 5G NR NSA test cases and has enabled the activation of GCF certification for 5G NR standalone devices. Keysight's 5G Conformance Toolset offers the widest range of GCF 5G NR radio frequency and protocol test cases for NSA and SA modes.

Analog Devices updates RadioVerse to support transition to 5G technology

Analog Devices (ADI) has announced an update to its RadioVerse technology and design ecosystem, which is intended to simplify and accelerate radio development for wireless carriers and telecom equipment manufacturers as they transition cellular base stations from 4G to 5G technology.

ADI's expanded RadioVerse portfolio features new radio transceiver hardware, software tools and a robust design environment designed to enable the more compact and lower power radios required for next generation networks. The new solution allows customers to evaluate and develop radio designs for 4G small cell and Pre-5G massive MIMO systems, which will be key elements in the transition to 5G.

Supporting radio design across the circuit, architecture, system and software levels, the updated RadioVerse release includes the AD9375 RF transceiver, the latest addition to ADI's integrated wideband RF transceiver series. The AD9375 device is claimed to be the first RF transceiver to incorporate digital pre-distortion (DPD) algorithm on-chip to help reduce DPD power consumption by up to a claimed 90% versus competing solutions.

ADI stated that re-partitioning the DPD system from the FPGA to the transceiver reduces the number of JESD204B serial data interface lanes by half, resulting in a significant power saving, particularly as the number of antennas per base station increases from two to 128 in support of Pre-5G massive MIMO radio-channel density requirements.

Further benefits of the new design include a more compact radio circuit layout enabling simplified routing and system design, reduced base station size and allowing the use of lower-cost, less complex FGPAs. Applied to small cells, these advantages can allow more frequency bands per cell for higher network capacity.

ADI's AD9375 transceiver allows a common radio platform design that is tunable over a range of 300 MHz to 6 GHz, operates on a 6 Gbit/s JESD204B interface and consumes less than 5 Watts. As with the AD9371 product, the AD9375 features two 100 MHz receivers, two 250-MHz transmitters, a two-input observation receiver and a three-input sniffer receiver. In addition, integrated DPD can support 3G and 4G waveforms with instantaneous signal bandwidth up to 40 MHz.

In addition to the AD9375, the RadioVerse transceiver hardware portfolio features wideband devices for base station architectures ranging from macro- to pico- and femto-cell form factors, in addition to ultra-low power, narrowband transceivers targeting industrial Internet of Things applications.


ADI noted that it is continuing to expand RadioVerse through partnerships with power amplifier (PA) suppliers including NXP Semiconductors and Skyworks Solutions.
