Precision RF Connectors and Adapters
Fairview Microwave precision RF connectors and adapters are designed for high-frequency, MIL-SPEC, and mission-critical applications
Fairview Microwave, an Infinite Electronics company, provides a comprehensive portfolio of precision RF connectors, adapters, and interconnect components designed for high-frequency and mission-critical applications. Engineered for consistent electrical performance, these components support reliable signal transmission across RF, microwave, and millimeter-wave (mmWave) systems where low loss and impedance control are essential.
These RF connectors and adapters are manufactured with precision-machined interfaces and tightly controlled 50 ohm impedance to minimize insertion loss and return loss. Available in industry-standard interfaces such as SMA, SSMC, and N-type configurations, they enable seamless integration across test systems, communication equipment, and RF subsystems.
Select components within this portfolio meet MIL-SPEC requirements, making them suitable for aerospace and defense applications where durability, reliability, and environmental performance are critical. With a wide range of configurations, including straight, bulkhead, and adapter designs, these components provide flexibility for system design and high-frequency interconnect solutions.
