Phase Matrix

Phase Matrix

Phase Matrix was a US-based manufacturer specializing in microwave frequency synthesis and precision measurement instrumentation. The company developed high-performance microwave frequency counters and synthesized signal sources covering frequencies from the MHz range into the millimeter-wave spectrum. Phase Matrix products were engineered for demanding applications in defense electronics, aerospace systems integration, and telecommunications testing where precise frequency measurement and stable signal generation are critical requirements.

The company's frequency counters, including the 548B series, deliver high-accuracy measurement of microwave signals in both laboratory and field environments. Phase Matrix was subsequently acquired by National Instruments (NI), with its product lines integrated into NI's RF and microwave test portfolio.

Key Product Lines

• Microwave Frequency Counters: High-accuracy counters for measuring signals across microwave and millimeter-wave frequency bands
• Microwave Signal Sources: Synthesized signal generators providing stable, low-phase-noise outputs across microwave frequencies
• RF Test Systems: Integrated solutions for microwave component and subsystem characterization

Industries Served

Phase Matrix instruments are used in aerospace and defense for radar system testing and electronic warfare characterization, in telecommunications for signal analysis and infrastructure verification, and in R&D laboratories focused on microwave component and circuit development.
