Agilent/Keysight Bulkhead (ff)

The Agilent/Keysight Bulkhead (ff) is a female-to-female coaxial adapter engineered for panel or enclosure mounting in RF and microwave signal chains. This bulkhead-mount adapter connects two female-terminated cables through a single chassis penetration, delivering 50 Ohm impedance with minimal reflections across a broad frequency spectrum. The integrated nut and washer assembly ensures mechanical stability, while gold or nickel-plated contacts and stainless steel or brass construction resist corrosion in demanding environments. Signal integrity remains preserved through low VSWR characteristics across all supported frequency ranges.

– Technical Specifications

Electrical:
• Impedance: 50 Ohms
• Frequency range varies by connector type:
– Type-N: up to 12 GHz (some versions to 18 GHz)
– 3.5mm: up to 26.5 GHz or 33 GHz
– 2.4mm: up to 50 GHz
– 2.92mm: up to 40 GHz
– 1.0mm: up to 110 GHz
• VSWR performance: 2.92mm connectors exhibit 1.25:1 maximum; 3.5mm typically better than 1.05

Physical:
• Configuration: Female-to-female, bulkhead-mount
• Materials: Stainless steel and brass with gold or nickel plating
• Environmental sealing: O-ring equipped on select models

– Key Features

• Connector types include Type-N, SMA, 3.5mm, 2.4mm, 2.92mm, and 1.0mm
• Low reflection design minimizes insertion loss across frequency bands
• Chassis-panel mounting with integrated hardware for secure installation
• Mating compatibility across multiple connector generations (2.92mm mates with SMA and 3.5mm; 2.4mm compatible with SMA, 3.5mm, and 2.92mm via adapters)

– Typical Applications

• RF and microwave test and measurement setups
• Communication system signal distribution
• High-frequency laboratory instrumentation
• DC to multi-gigahertz signal routing

– Compatibility & Integration

Common Keysight reference models include the 83059B (3.5mm, DC to 26.5 GHz) and 5062-7243 (2.4mm female-to-female chassis bulkhead). Connector selection determines operating frequency and mating partnerships with external RF assemblies.
