The Agilent/Keysight 11923A is a precision 1.0 mm female connector launch engineered to transition microwave circuits from microstrip to coaxial topology. Operating across DC to 110 GHz, this adapter integrates into test systems including the Keysight 8510XF and N5250A, enabling direct connection of coaxial test equipment to microstrip circuitry within custom packages and fixtures.
Technical Specifications
• Connector Type: 1.0 mm female
• Frequency Range: DC to 110 GHz
• Center Pin Diameter: 0.162 mm
• Dielectric Interface: Air dielectric supported by low-loss plastic bead
• Sealing Interface: Glass-to-metal seal
• Mounting Method: Threaded installation into package or fixture housing
– Key Features
• Precision microstrip-to-coaxial transition geometry
• Air dielectric construction with low-loss plastic bead support minimizes insertion loss across the full frequency range
• Glass-to-metal seal interface provides robust environmental protection
• Pre-assembled launch arrives ready for integration
• Quasi-hermetic sealing achievable via epoxy application to threads prior to installation
• Supplied with machining details and assembly documentation
– Typical Applications
• On-wafer and coaxial measurements requiring microstrip-to-coaxial transition
• Integrated circuit and module characterization at millimeter-wave frequencies
• Test fixture integration for packaged devices and custom assemblies
• High-frequency broadband circuit evaluation
– Compatibility & Integration
The 11923A threads directly into custom package and fixture housings. Final installation requires user-performed machining of the housing and direct connection of the 0.162 mm center pin to the microwave circuit card. Primary compatibility includes Keysight 8510XF and N5250A systems. The launch accommodates test systems operating up to 110 GHz, supporting both on-wafer and coaxial measurement configurations.
