Open RAN Massive MIMO Radio Units—American-Designed, O-RAN CertifiedPage Topics
Building the American 5G Radio layer for Open RAN
AmpliTech designed and commercialized the only American Open RAN-compliant 64T64R Massive MIMO radio unit, OTIC certified and built from the chip up.

Open RAN didn’t create a new market for AmpliTech. It gave a name to something we have already spent two decades preparing for: RF engineering precise enough that the radio itself stops being the constraint on network performance.
O-RAN Architecture: How Open RAN Is Changing the Mobile Landscape
Our LNAs deliver industry-lowest noise figures across L, S, C, X, Ku, Ka, and millimeter-wave bands, in standard and custom configurations for commercial, military, and space-grade applications. Because we design our own MMIC chips in-house, the noise performance of these products cannot be replicated by suppliers using third-party components.
For most of the last two decades, a mobile network operator who chose a radio vendor was, in practice, choosing that vendor for the life of the deployment. The radio, the baseband, and the software that ran them came from the same company, using interfaces that only that company’s own equipment could speak.
Open RAN separates those layers and opens the interfaces between them, most consequentially, the fronthaul link between the radio unit and the distributed unit. A network built to O-RAN Alliance specifications can (in principle) mix radios, baseband, and software from different vendors in the same deployment.
Open RAN is intended to reduce operator dependence on vertically integrated, single-vendor network architectures by allowing components to be sourced from multiple suppliers. For a company like AmpliTech, that architectural shift creates the opportunity to compete specifically at the radio layer, on radio performance, without having to supply an operator’s entire proprietary network stack. This is the commercial opening Open RAN creates, and it’s the one AmpliTech is built to take.
That “in principle” is also the whole technical story. An open interface is a starting point, not a guarantee. Two radios can both claim O-RAN compliance and still fail to interoperate cleanly in a live, multi-vendor network. The gap between compliant on paper and interoperable in the field is where most of the real engineering work actually lives.
AmpliTech’s Role in the Open RAN Radio Layer
AmpliTech builds the radio unit, the piece of the network that has to perform in the physical world, not just on a spec sheet. It’s the layer with the least room for error: The signal either has the fidelity to carry the network’s capacity, or it doesn’t, and no amount of software optimization further up the stack fixes a radio that’s noisy at the front end.
That’s the layer AmpliTech has spent 25 years in. AmpliTech’s Massive MIMO radio units are O-RAN Alliance–compliant and independently certified, and the company is the only American manufacturer to have designed and commercialized an Open RAN-compliant 64T64R Massive MIMO radio unit, with 64 transmit and 64 receive RF paths/channels, the configuration carriers use for the highest-capacity macro deployments.
Chip-Level Engineering
Most radio manufacturers assemble their radios from merchant-market components, including the RF chips that determine how clean the signal actually is. Their performance ceiling is set by whatever their component suppliers choose to sell them. AmpliTech doesn’t buy that component. The MMIC low-noise amplifiers inside every AmpliTech radio unit are designed in-house, by AGMDC, AmpliTech’s own chip design division. That’s the practical difference between us and a company assembling an O-RAN-compliant radio unit from outside parts: AmpliTech controls the RF performance of its radios at the chip level, not just at the systems-integration level. This vertical integration gives us greater control over critical RF performance characteristics, including noise performance and signal fidelity, rather than relying entirely on externally sourced RF components. It’s also the harder thing to replicate. A competitor can source a compliant radio design, but building the chip underneath it requires the RF and semiconductor engineering AmpliTech has spent 25 years accumulating.
From Certification to Commercial Deployment
AmpliTech’s Open RAN strategy has progressed beyond laboratory validation. The company has reported more than 3,000radios shipped and in service with a Tier-1 mobile network operator, demonstrating that its radio platform has moved from development and certification into commercial deployment. That distinction matters: a radio that performs in a lab and a radio that performs at scale, in a live carrier network, are not proven by the same evidence. AmpliTech has evidence of the second.
Independent Validation in Multi-Vendor Open RAN Environments
Commercial deployment is the headline proof point. The technical validation behind it is what makes that deployment possible:
O-RAN Global PlugFest.
AmpliTech’s 64T64R radio was the only radio of its class represented at the event, tested alongside baseband and software from other vendors in the kind of multi-vendor configuration Open RAN is meant to enable.
AI-RAN demonstration with Northeastern University.
AmpliTech’s 64T64R radio has served as the hardware platform in joint AI-RAN testing with Northeastern University’s Open6G OTIC, pairing the radio with AI-native software and compute from partners building the next layer of the stack.
FCC and ISED Canada certification.
AmpliTech’s 5G radio hardware has cleared independent certification in both the U.S. and Canadian markets, the regulatory baseline for commercial deployment.
A Domestic Open RAN Option: American-Designed 5G Infrastructure
Most of the radio hardware in North American 5G networks is designed and built outside the United States. That’s a supply chain fact with real consequences for operators and for policymakers who care about where critical communications infrastructure comes from and who controls it.
AmpliTech designs and engineers its 5G radio technology in the United States, including proprietary chip-level RF components developed by its AGMDC division. For operators evaluating Open RAN specifically because it opens the door to vendor diversity, that makes AmpliTech one of the few paths to that diversity that doesn’t run through a foreign supply chain.
AmpliTech’s Open RAN Roadmap
AmpliTech’s Open RAN business is the fastest-growing part of the company, and it’s still early. The engineering work, closing the gap between spec-compliant and field-proven, is the same work the company has always done, applied to a newly open architecture.
AmpliTech is expanding beyond its flagship 64T64R Massive MIMO platform with additional macro, small cell/pico cell, low-power, and medium-power private 5G Open RAN radio configurations, designed to address carrier, private-network, and next-generation AI-enabled deployments.
Beyond today’s 5G deployments, AmpliTech is positioning its Massive MIMO platform for emerging AI-RAN and 6G architectures, where advanced radio performance and programmable, multi-vendor networks are expected to converge.
