The introduction of MaxLinear's MXL17xxx family of devices, known as Sierra, signifies a substantial advancement in the telecommunications sector, specifically within the rapidly evolving Open RAN (O-RAN) ecosystem. Sierra's system-on-chip (SoC) design addresses the critical industry need for more efficient and cost-effective radio units (RUs) by providing a comprehensive, software-programmable radio signal processing engine.
By integrating multiple subsystems into a single chip, including RF transceiver, Digital Front End (DFE) and Low-PHY baseband processor, Sierra not only simplifies the design and reduces the development time of new O-RUs, but also offers scalability from macro to picocell applications. This scalability is crucial as it allows infrastructure vendors to address a range of network deployments with a unified platform, potentially leading to reduced inventory complexities and enhanced supply chain management.
The inclusion of digital pre-distortion (DPD) for power amplifiers (PAs) is particularly noteworthy. DPD is a technique used to correct the nonlinearities in PAs, which if left uncorrected, can lead to signal distortion and inefficiency. MaxLIN, the DPD solution within Sierra, supports up to 400MHz of occupied bandwidth and exceeds regulatory requirements for emissions, indicating a strong commitment to both performance and environmental standards.
MaxLinear's launch of the Sierra platform is poised to have a significant financial impact on the company and the broader market for radio access network components. As stated by Stefan Pongratz of the Dell’Oro Group, the Open RAN market is expected to constitute a substantial portion of global RAN revenues by 2028. MaxLinear's strategic entry with a product that targets this growth segment can bolster its market position and potentially increase its revenue streams.
From an investment perspective, the ability of Sierra to reduce the size, weight, power and cost (SWaP-C) of radio units aligns with the industry's drive towards more sustainable and cost-efficient network infrastructure. This alignment with market trends is likely to be well-received by investors, as it demonstrates MaxLinear's responsiveness to market demands and its potential for capturing a larger share of the O-RAN market.
Furthermore, the announcement of Sierra's capabilities being demonstrated at MWC 2024 serves as an anticipatory catalyst for MaxLinear's stock. Such demonstrations can often lead to partnerships, contracts and increased visibility among potential customers, which can positively influence investor sentiment and possibly the stock price.
The Sierra platform's focus on reducing the environmental footprint of wireless infrastructure through improved power amplifier efficiency and lower overall energy consumption is a critical aspect of its market appeal. MaxLIN's advanced DPD algorithms, which enhance PA efficiency, directly contribute to minimizing the energy consumption of radio units. This is not only beneficial from a cost perspective but also aligns with global initiatives to reduce carbon emissions in the telecommunications industry.
As companies and investors increasingly prioritize sustainability, MaxLinear's emphasis on energy-efficient solutions could enhance its brand reputation and appeal to environmentally conscious stakeholders. The ability to exceed 3GPP and FCC emissions requirements further solidifies the company's commitment to sustainability, which could lead to competitive advantages in an industry where regulatory compliance and environmental impact are becoming increasingly important decision factors.

Sierra integrates the following sub-systems into a single chip, providing a complete software-programmable radio signal processing engine for Open RUs (O-RU):
RF transceiver supporting up to 8 transmitters, 8 receivers, and 2 feedback receivers
Digital Front End (DFE) including DPD, crest factor reduction (CFR), and Passive Intermodulation (PIM) cancellation
Low-PHY baseband processor supporting 5G, 4G, and NB-IoT air interfaces
O-RAN Alliance Split 7.2x fronthaul interface
“Infrastructure vendors have been waiting for an open-market silicon solution that can enable them to develop O-RUs without compromise on performance or cost,” said Sean Martin, Senior Director of Wireless Infrastructure. “By integrating our highest performance RF and system technologies in Sierra, MaxLinear is empowering these radio vendors to rapidly and cost effectively develop new O-RUs with reduced size, weight, and power consumption.”
Sierra’s complete system integration yields a feature-rich, high-performance RU building block with low power consumption, board footprint, and implementation cost that reduces the need for multiple FPGAs/ASICs and massively simplifies new O-RU development. Designers can rapidly build new macro and picocell O-RUs using just a single Sierra device by adding an appropriate RF front end. Massive MIMO O-RU are created by tiling an array of Sierra devices and connecting them to a central beamforming solution. This system modularity and flexibility makes Sierra an ideal radio platform building block to maximize design reuse and dramatically speed up the development of new O-RUs.
“Open RAN momentum continues to build and is set to account for 20 percent to 30 percent of worldwide RAN revenues by 2028,” said Stefan Pongratz, Vice President and Analyst at the Dell’Oro Group. “New optimized off-the-shelf O-RU silicon solutions like Sierra play an essential role to enable improved radio supplier diversity.”
At the heart of Sierra is MaxLIN™, MaxLinear’s leading field-proven DPD solution for wideband power amplifier linearization, supporting up to 400MHz of occupied bandwidth. MaxLIN’s linearization performance exceeds the 3rd Generation Partnership Project (3GPP) and U.S. Federal Communications Commission (FCC) unwanted emissions requirements with margin while delivering high PA efficiency, thereby minimizing RU energy consumption, and making radios lighter and more cost-effective. MaxLIN’s advanced algorithms feature enhancements to correct for both long-term and short-term nonlinear dynamics including GaN charge trapping and thermal transients, critical for high-power Macro applications. It optimally supports different power amplifier (PA) architectures, technologies, and power levels for all potential RU applications from macro to picocells. In addition, OEMs also have the option to implement their own DPD using the Sierra on-chip compute resources.
More about Sierra
Sierra’s RF transceiver uses a low power wide band Zero-IF (ZIF) architecture and supports 8 transmitters (TX) and 8 receivers (RX) with 2 feedback receivers (FBRX). Each RX supports wide signal bandwidths up to 400MHz and each TX and FBRX supports signal bandwidths up to 900MHz. It can operate in 8T8R single-band or 2 x 4T4R multi-band configurations.
The digital front-end (DFE) integrates digital pre-distortion (DPD), crest factor reduction (CFR), passive intermodulation cancellation (PIMC), digital up conversion (DUC), and digital down conversion (DDC) blocks. MaxLinear's advanced DPD/CFR technology, MaxLIN™, linearizes power amplifiers (PA) up to 400MHz of occupied bandwidth and dramatically improves PA energy efficiency while meeting spectral emission masks with margin. The PIMC block cancels passive intermodulation products in the uplink paths to improve receiver sensitivity and relax the specification of expensive RF filters. The DUC/DDC supports up to eight component carriers per transmit and receive path.
