Copper Mountain Unlocks Affordable mmWave Testing with New VNA-less Solution

INDIANAPOLIS, IN – April 23, 2026 – Copper Mountain Technologies (CMT) today announced a significant development aimed at making high-frequency testing more accessible and cost-effective with the launch of its BFx-02 Frequency Extension Base. Unveiled at the EuCAP Exhibition in Dublin, the new patent-pending solution is designed to simplify millimeter-wave (mmWave) S-parameter measurements by removing the need for a full-featured Vector Network Analyzer (VNA) in frequency extension setups.

This move positions the Indianapolis-based company to address a major bottleneck in the development and production of next-generation electronics. As technologies like 5G, autonomous driving, and advanced satellite communications push frequencies higher into the mmWave spectrum, the cost and complexity of testing have become a substantial barrier to entry for many organizations. The BFx-02 aims to dismantle that barrier by offering a streamlined, purpose-built alternative to traditional, and often prohibitively expensive, test configurations.

A New Paradigm for High-Frequency Measurement

Traditionally, performing S-parameter measurements at mmWave frequencies has required a sophisticated and costly setup. Engineers typically start with a high-performance, multi-port VNA mainframe and connect it to external frequency extender modules, or heads, which upconvert the VNA's signals into the desired mmWave range. While effective, this approach ties up a valuable and expensive VNA, often costing tens or even hundreds of thousands of dollars, for a single test station.

Copper Mountain Technologies' BFx-02 fundamentally changes this equation. It functions as a dedicated base station, providing all the necessary radio frequency (RF) and local oscillator (LO) signals required to drive the frequency extenders directly. With RF output power up to +20 dBm and a frequency range of 4 GHz to 20 GHz, the device is powerful enough to support long cable runs common in test labs and production floors. Its architecture is purpose-built for this task, replacing the VNA mainframe entirely within the frequency extension setup.

Crucially, the BFx-02 is designed for universal compatibility, allowing users to pair it with any frequency extenders on the market. This flexibility lets engineering teams select extender modules that best fit their specific performance needs and budget, rather than being locked into a single vendor's ecosystem. The system also features thoughtful design elements for practical deployment, such as side-panel connectors that simplify integration into test racks and reduce stress on cabling.

Though it replaces the VNA mainframe, the BFx-02 system comes with a robust software suite that delivers the powerful analysis capabilities engineers expect. Standard features include linear and logarithmic sweeps, power sweeps, time-domain analysis with gating, and fixture simulation for embedding and de-embedding. This ensures that the simplified hardware approach does not compromise on measurement integrity or analytical depth.

Disrupting a Concentrated Market

The launch of the BFx-02 comes at a critical time for the electronics industry. The global market for millimeter-wave test equipment is booming, with some analysts projecting it will grow from over $40 billion in 2024 to nearly $63 billion by 2031. This growth is fueled by the relentless demand for higher bandwidth and faster data rates. However, the market is highly concentrated, with established giants like Keysight, Rohde & Schwarz, and Anritsu commanding a significant share.

These industry leaders offer comprehensive and powerful mmWave solutions, often featuring VNA systems capable of measurements up to 220 GHz and beyond. Their offerings represent the gold standard in performance but come with a price tag that can be a major hurdle for startups, smaller companies, and even large organizations looking to scale up production testing.

The BFx-02 differentiates itself not by trying to outperform these high-end systems on every metric, but by creating an entirely new category of test equipment. By decoupling the mmWave measurement from the VNA, it lowers the capital expenditure required to establish a high-frequency test bench. This approach democratizes access to a critical technology, enabling more engineers and companies to innovate in the mmWave space.

Unlocking Production Efficiency and Scalability

Beyond R&D labs, the BFx-02's most significant impact may be felt on the factory floor. In high-volume production environments, test throughput is paramount. The traditional one-VNA-per-station model creates a significant bottleneck and inflates costs when scaling up.

The ability of the BFx-02 to operate independently frees up existing full-featured VNAs for more complex characterization tasks that require their full capabilities. This allows a company to create multiple parallel mmWave test stations for production or automated test equipment (ATE) applications, each using a relatively low-cost BFx-02 base, without needing to purchase an equal number of expensive VNAs. This dramatically improves resource allocation and increases overall test throughput.

This scalable model is particularly beneficial for contract manufacturers and original equipment manufacturers (OEMs) who need to rapidly expand their testing capacity to meet demand. The streamlined configuration also reduces the number of potential failure points and simplifies maintenance, further enhancing its appeal for production deployment.

Accelerating Innovation in 5G, Automotive, and Beyond

The availability of a more accessible and scalable mmWave test solution has far-reaching implications across several key industries. In the telecommunications sector, the rollout of 5G and the development of future 6G networks rely heavily on mmWave frequencies to deliver promised speeds and low latency. The BFx-02 can help accelerate the development and manufacturing of the components and beamforming antenna systems that are central to these networks.

In the automotive industry, 77 GHz radar systems are becoming standard for advanced driver-assistance systems (ADAS) and are a cornerstone of autonomous driving technology. Efficient and reliable production-line testing of these radar modules is critical for safety and performance. By lowering the cost of S-parameter testing, the BFx-02 can help streamline this process, contributing to faster development cycles and potentially wider adoption of these life-saving technologies.

Similarly, the satellite communications (SATCOM) industry is increasingly turning to mmWave to provide high-throughput data from orbit. As companies race to build out new satellite constellations, the pressure to reduce costs and accelerate manufacturing is immense. The BFx-02 provides a valuable tool for developers and manufacturers of satellite components and ground station equipment, enabling them to validate performance without breaking the budget.

By addressing the fundamental challenges of cost and complexity, this new technology from Copper Mountain Technologies stands to do more than just simplify measurements. It acts as an enabler, empowering a broader range of innovators to push the boundaries of what is possible with high-frequency technology and helping to bring the next generation of connected devices to market faster.
