SV Microwave Adapters & Terminations

SV Microwave adapters and terminations extend Amphenol Military & Aerospace’s precision RF portfolio into laboratory test, military flight, and embedded mission electronics. These components maintain 50 Ω impedance and low VSWR across broad frequency ranges from DC to the mmWave band, linking SMA, SMP, SMPM, SMPS, BNC, TNC, N‑Type, and 1.0 mm series interfaces.

Adapter Configurations

Engineers can select adapters to meet dimensional and interface requirements for micro‑ to mmWave systems including:

• In‑series and between‑series adapters for transitions between common RF standards such as SMA‑to‑SMPM or 2.4 mm‑to‑2.92 mm.
• Right‑angle and bulkhead styles for tight routing and panel feed‑through applications.
• Floating and blind‑mate versions compatible with VITA 67.3 and SOSA‑aligned embedded module hardware.
• Hermetic RF adapters with glass‑to‑metal sealing for pressurized bays and thermal‑vacuum test conditions.
• Precision test adapters optimized for repeatable calibration in broadband instrumentation and VNA setups.

Terminations and Loads

SV Microwave terminations provide calibration‑grade matched loads for production test equipment and high‑frequency modules. Available in standard and hermetic forms, these components maintain controlled impedance and low return loss across defense and aerospace bands. Designs reference MIL‑PRF‑39012 and M83517 criteria for reliability in harsh environments.

Engineering Integration

Each adapter is precision‑machined using aerospace‑grade CNC methods to preserve concentricity and dimension control, resulting in high repeatability and phase stability. Gold‑plated center contacts and corrosion‑resistant shell materials such as stainless steel and tri‑nickel finishes enhance durability under vibration and temperature stress. These designs interface seamlessly with SV Microwave ConvergeRF cable assemblies to create continuous low‑loss signal paths between modules and test fixtures.

Applications

• Radar and phased array test lines and feed traces
• Electronic warfare receivers and transmit paths
• Ka‑band SATCOM terminals and payload integration
• SOSA/OpenVPX embedded payload interconnect and qualification testing
• Calibration and metrology benches for RF instrumentation

Together with SV Microwave high‑frequency and mil‑qualified connectors, these adapters and terminations enable a comprehensive Amphenol RF ecosystem for defense and aerospace architectures requiring consistent performance up to 110 GHz.
