High-Frequency Precision Test Adapters

Molex High-Frequency Precision Test Adapters feature numerous interfaces that include 2.92mm (40GHz), 2.4mm (50GHz), 1.85mm (67GHz) and 1.0mm (110GHz). These adapters feature intermateability that provides design flexibility, making it possible to mate 2.4mm with 1.8mm connectors or mate 2.9mm connectors with SMA or 3.5mm connectors. Within and between series are available, offering any combination for every situation. The precision-machined interfaces are ideal for precise laboratory measurements, while the excellent electrical performance ensures accurate and repeatable results. These adapters have a wide frequency range from 40GHz up to 110GHz, providing a range of capabilities. Molex High-Frequency Precision Test Adapters are suitable for network systems, 5G applications, high-speed data transmission and automated test equipment.
