Agilent/Keysight 11853A

The Agilent/Keysight 11853A is a 50-ohm Type-N accessory kit engineered for RF and microwave measurements with network analyzers and S-parameter test sets. The kit delivers essential RF components and calibration aids needed for precise characterization of 50-ohm Type-N devices, supported by a complete set of shorts and barrel adapters housed in a protective storage case.

– Technical Specifications

• Connector Type: Type-N (male and female)
• Impedance: 50 ohms
• Return Loss (adapters): Typically 40 dB up to 1.3 GHz
• Net Weight: 0.91 kg (2 lb)
• Shipping Weight: 1.36 kg (3 lb)
• Dimensions: 168 mm × 114 mm × 51 mm (6 5/8″ × 4 1/2″ × 2″)

– Key Features

Kit Contents:
• 1 × Type-N female short
• 1 × Type-N male short
• 2 × Type-N male barrels
• 2 × Type-N female barrels
• Storage case with foam pad (Keysight 9220-2550)
• Operating and Service Manual (Keysight 11853-90003)

The adapter configuration supports flexible interconnection between Type-N test ports and devices. Shorts enable calibration reference planes; barrels extend or transition connections. All components maintain 40 dB return loss performance through 1.3 GHz, critical for network analyzer calibration accuracy and measurement fidelity.

– Typical Applications

S-parameter measurement and device characterization on 50-ohm Type-N systems. Calibration kit integration for network analyzers. RF component testing and validation in microwave development environments.

– Compatibility & Integration

Direct compatibility with:
• HP 8753E Network Analyzer (Option 011)
• HP 85046A S-parameter Test Set (50-ohm)
• HP 85047A S-parameter Test Set (50-ohm)
• HP 11850C Network Analyzer Keyboard

Optional ancillary equipment includes Type-N gage sets, calibrated torque wrenches (136 N-cm / 12 in-lb), and connector care documentation. Connectors require end-cap protection when idle and demand cleanliness maintenance; worn components are not field-serviceable.
