Keysight / Agilent / HP 11667C Power Splitter

The Keysight 11667C Power Splitter is a precision RF/microwave signal divider engineered to distribute signals with exceptional amplitude and phase tracking across demanding test and measurement applications. Operating from 0.1 GHz to 18 GHz, it delivers consistent power distribution, signal routing, power leveling, and calibration functionality in laboratory, manufacturing, and research environments.

## Technical Specifications

• **Frequency Range:** 0.1 GHz to 18 GHz
• **Impedance:** 50 Ohms
• **Maximum Input VSWR:** 1.20:1
• **Insertion Loss:** ≤ 3.7 dB (at 18 GHz)
• **Isolation:** ≥ 25 dB (at 18 GHz)
• **Amplitude Balance:** ≤ 0.5 dB (over specified frequency range)
• **Phase Balance:** ≤ 5 degrees (over specified frequency range)
• **Power Handling:** 1 Watt average, 100 Watts peak
• **Connectors:** Type-N Female

## Key Features

Amplitude balance within ±0.25 dB maintains signal fidelity across the full frequency range. Phase tracking of ±5 degrees ensures coherent signal distribution for phase-sensitive applications. Low insertion loss at 18 GHz minimizes signal degradation in high-frequency measurements. High isolation exceeding 25 dB at 18 GHz provides port-to-port decoupling. Input VSWR of 1.20:1 indicates minimal reflections at the source port.

## Physical Characteristics

Compact form factor: 4.3 inches length × 0.6 inches width × 0.6 inches height. Weight of 0.33 lb enables integration into portable test systems and bench configurations.

## Typical Applications

Signal routing in multi-path test setups. Power leveling across parallel measurement channels. Calibration reference distribution in network analyzer and spectrum analyzer systems. Phase-matched signal splitting for interferometric and coherent measurement techniques.

## Compatibility & Integration

Type-N Female connectors provide direct interface with standard RF and microwave instruments. The 0.1–18 GHz bandwidth accommodates signal generators, spectrum analyzers, network analyzers, and related equipment operating within this frequency band. 50 Ohm impedance ensures compatibility with standard RF system architectures.
