Copper Mountain Technologies, a leading RF test equipment manufacturer, has launched the BFx-02, its new patent-pending Frequency Extension Base. This solution is designed to simplify and reduce the cost of mmWave S-parameter measurement. It provides the RF, LO, and IF signal infrastructure required to operate frequency extenders, eliminating the need for a full-featured vector network analyzer (VNA) at each frequency extension setup. Traditionally, a VNA handles both signal generation and measurement, making mmWave systems costly and bulky. By separating signal generation into a dedicated device, the BFx-02 enables more streamlined, accessible, and reliable test configurations with fewer points of failure.
Measurement of the device under test is still performed using VNA-based analysis. However, the BFx-02 separates the signal-feeding function from the measurement function. It is compatible with frequency extenders from multiple vendors, allowing users to select extension hardware based on their specific requirements. The device provides RF output power of up to +20 dBm to support longer cable runs and uses side-panel connectors to simplify integration and reduce cable strain.
By decoupling mmWave signal generation from the VNA, the BFx-02 allows existing instruments to be reused elsewhere and enables multiple parallel test setups. This means higher throughput and lower cost of deploying mmWave S-parameter measurement systems in research, production, automated test equipment, and OEM environments. Target applications include automotive radar, 5G beamforming systems, satellite communications, and aerospace systems.
The product is being unveiled at the EuCAP Exhibition in Dublin in the joint Compass Technology Group/Copper Mountain Technologies Booth.
