Agilent/Keysight 11903D

The Agilent/Keysight 11903D is a metrology-grade calibration adapter for interconnecting 2.4 mm female and Type-N male connectors in RF and microwave test systems. Engineered for signal integrity across DC to 18 GHz, this adapter delivers the electrical performance required for precision measurement applications where connector compatibility spans dissimilar interface standards.

– Technical Specifications

• Connector 1: 2.4 mm Female
• Connector 2: Type-N Male
• Frequency Range: DC to 18 GHz
• Return Loss: > 28 dB
• Repeatability: −48 dB
• Electrical Length: 46.1 mm (1.85 in)
• Overall Length: 50.0 mm (1.97 in)
• Diameter: 22.0 mm (0.86 in)

– Key Features

Return loss exceeding 28 dB ensures minimal reflections across the operating bandwidth, critical for accurate signal characterization. The −48 dB repeatability specification supports calibration workflows where connector mating and unmating cycles demand stable electrical performance. Physical dimensions—50.0 mm overall length and 22.0 mm diameter—integrate efficiently into test benches with space constraints.

– Typical Applications

• Industrial RF and microwave measurement systems
• Test and measurement environments requiring 2.4 mm to Type-N transitions
• RF communications test configurations

– Compatibility & Integration

Designed specifically for Keysight microwave and RF test systems, the 11903D provides direct integration with platforms expecting Type-N male input and 2.4 mm female output configurations. Its DC to 18 GHz bandwidth accommodates both narrowband and broadband measurement requirements within this frequency envelope.
