MaxLinear Microwave Transceiver SoC Powers Aviat Networks’ new WTM 4000 Microwave Radio Platform with Adaptive Dual Carrier (A2C) Operation

February 15, 2018
  • Aviat WTM 4000 delivers two independent channels in single frequency band supporting 5G transport; New feature is enabled by MaxLinear’s MXL11xx series CMOS transceiver

MaxLinear, Inc. (NYSE:MXL), a leading provider of radio frequency (RF), analog and mixed-signal integrated circuits for the connected home, wired and wireless infrastructure, and industrial and multimarket applications, today announced that Aviat Networks (NASDAQ: AVNW) has selected the MxL11xx CMOS transceiver to enable channel aggregation functionality on its new line of WTM 4000 microwave radios.

Tier-1 carriers at Mobile World Congress will be among the first to get a demonstration of the new capability.

Aviat is a global provider of microwave networking products and services to mobile service providers, government agencies, energy and transportation companies and enterprises. The WTM 4000 is the industry’s highest capacity microwave radio platform and features the highest capacity in single transceiver radio. The adaptive dual carrier (A2C) feature enables two RF channels over a single transceiver, doubling the capacity of a single-header radio.

The MaxLinear MxL11xx is an all-CMOS, single-chip broadband microwave transceiver product family that can support operation of all licensed and unlicensed bands from 5 GHz to 45 GHz, including all ETSI-defined channel spacing options from 5MHz to 224MHz. Single- or dual-channel operational modes are available.

The comprehensive frequency support of the MxL11xx greatly reduces the number of product configurations that Aviat must develop. The high level of integration also greatly minimizes external bill of material content, while supporting advanced features like digital pre-distortion, and channel aggregation and calibration.  The channel aggregation feature is ideal for 5G backhaul applications, doubling the available capacity on a single backhaul link.

“For Aviat, the comprehensive transceiver functionality of the MxL11xx together with our software and systems expertise enables us to provide our customers with a highly-differentiated microwave solution,” said Ola Gustafsson, Senior Vice President and Chief Product Officer, Aviat Networks. “A2C operation with a single transceiver offers an attractive combination of maximal bandwidth throughput, low latency and smaller form factor.”

“With the evolving requirements of 5G backhaul and fronthaul, particularly higher capacity requirements, operators are looking for new technology solutions. MaxLinear’s MxL11xx offers highly advanced features with a high level of integration, unmatched performance over a wide frequency range of operation, and low power consumption, which meets strict transmission specifications,” said Brendan Walsh, Vice President of Product Line Marketing, Infrastructure Group. “We’re pleased to be partnering with Aviat Networks in its development of the WTM 4000 high capacity microwave radio platform.”

Technical Details

The MxL11xx features built-in Full Spectrum Capture™ (FSC™) technology and supports channel aggregation mode, enabling a second channel with any channel spacing to be processed within the same IC.

The MxL11xx incorporates a full receive, transmit, feedback path, and all synthesizer components on a single chip, and can support code rates up to 4096 QAM. The closed-loop digital pre-distortion provides power amplifier (PA) linearization for a wide variety of PAs.

The product is now available in volume production quantities from MaxLinear’s worldwide sales team. For more information, email
