Standard Interface RF PCB Connectors

Amphenol Military & Aerospace Standard Interface RF PCB Connectors manufactured by SV Microwave deliver precision single‑port 50 Ω coaxial interfaces for high‑frequency radar, electronic‑warfare, SATCOM, and instrumentation modules. Configured for direct board integration, these connectors extend standard SMA through 1.85 mm series performance to the PCB level with reliable impedance continuity from DC to 100 GHz.

Connector Series and Frequency Coverage

• SMA Series: Threaded coupling interface typically usable to 18–26.5 GHz per MIL‑PRF‑39012 designs.
• SMP / SMPM / SMPS: Blind‑mate push‑on interfaces supporting compact module layouts to ~65 GHz; available in standard or QuarterBack bayonet‑locked SMPS forms for high‑vibration environments.
• 2.92 mm / 2.4 mm / 1.85 mm Precision Series: mmWave edge‑launch connectors offering broadband DC–100 GHz capability for next‑generation payloads.

Mounting and Attachment Styles

• Solderless compression‑mount: Enables quick installation and rework without PCB heat exposure.
• Soldered through‑hole or board‑mount: Provides robust mechanical retention with built‑in thru‑legs.
• Edge‑launch format: Ensures optimal collinear coax‑to‑PCB transition for lowest VSWR and reflection.
• Edge‑Lock option: Uses an interference‑fit pin to pull the connector flush to the board edge, eliminating fixturing and maintaining alignment during reflow.

Mechanical and Environmental Considerations

• Reflow‑stable dielectric variants tolerate soldering up to ~500 °C without electrical degradation.
• Available in stainless‑steel or passivated brass bodies with RoHS‑compliant plating finishes for corrosion resistance.
• Compression and locking variants improve vibration resilience for defense and aerospace service environments.

Design and Modeling Support

Encrypted HFSS and CST footprint models are available through SV Microwave for accurate electromagnetic simulation and stack‑up matching. Custom footprint designs can be supplied to accommodate unique board thickness or launch geometry requirements. Pre‑tinned variants simplify assembly on automated lines.

Applications

These single‑port PCB connectors serve as the foundation for SV Microwave’s multi‑port and ganged PCB solutions. Common deployment areas include:

• Radar and electronic‑warfare modules
• High‑speed embedded SOSA/OpenVPX computing cards
• RF switch matrices and instrumentation front‑ends
• Environmental and vibration‑exposed mil‑aero systems

Their broadband 50 Ω impedance control and reconfigurable mount options make them a primary choice for engineers seeking compact, low‑VSWR board‑level RF interfaces within defense and aerospace hardware architectures.
