Test & Measurement RF PCB Connectors

Amphenol Military & Aerospace’s Amphenol CDI Test & Measurement RF PCB Connectors provide precise, low‑VSWR 50 Ω transitions between coaxial transmission lines and high‑frequency printed circuit boards. Designed for automated test equipment and instrumentation, these connectors maintain impedance control and mechanical stability through microwave and mmWave frequencies.

Connector Styles

• Edge‑launch PCB connectors minimize signal path length and maximize impedance accuracy for frequencies up to 67 GHz.
• Surface‑mount variants support reflow assembly for compact, low‑profile boards and automated production processes.
• Thru‑hole mounts provide robust mechanical retention for vibration‑prone or high‑reliability environments.
• Compression‑mount designs enable solderless installation and rework for reconfigurable test modules.

Interface Options

Standard single‑port connectors are available in 1.85 mm (67 GHz), 2.4 mm (50 GHz), 2.92 mm / K (40 GHz), and 3.5 mm (26.5 GHz) interfaces. These are complemented by multi‑port families such as CoreHC™ and CoreGD™, which offer 2.5 mm‑pitch high‑density solutions with aggregate bandwidth extending to 65–100 GHz for dense board layouts and wafer‑level test channels.

Design and Integration

• Precision‑machined housings ensure consistent alignment and repeatable insertion loss across mating cycles.
• Mechanical stability supports controlled‑impedance coplanar‑waveguide and stripline launches.
• Compatible with automated SMT assembly or manual compression installation as required.

Applications

• Test and measurement instrumentation and ATE boards
• High‑frequency laboratory equipment and metrology systems
• Aerospace, defense, quantum/cryogenic, and industrial RF modules
• Compact multi‑port and high‑density PCB instrument architectures

These connectors combine robust mechanical construction, excellent impedance control, and reworkable configuration options—providing engineers with flexible board‑level interconnect solutions suited for broadband verification and advanced test environments.
