The Agilent/Keysight 0955-0704 is a 75 Ohm RF directional coupler engineered for microwave signal splitting and non-interfering measurement applications up to 1 GHz. This component delivers a coupled output of -10 dB ±0.5 dB with a 9 dB coupling factor and insertion loss below 2 dB, making it suitable for systems requiring precise signal extraction without degrading primary signal paths.
Technical Specifications
• Impedance: 75 Ohm
• Frequency Range: Up to 1 GHz
• Coupling Factor: 9 dB
• Coupled Output: -10 dB ±0.5 dB
• Insertion Loss: < 2 dB
• Connector Type: BNC (female)
– Key Features
The low insertion loss specification ensures minimal attenuation of the main signal path. The tight coupling output tolerance of ±0.5 dB supports accurate measurement calibration across the operating band. The 75 Ohm impedance aligns with cable television and video measurement standards.
– Typical Applications
• Non-interfering RF and video measurement injection in cable TV analyzers
• Signal splitting in 75 Ohm RF and microwave systems
• Test point access without primary signal interruption
– Compatibility & Integration
This coupler is specifically designed for integration with the Agilent/Keysight HP 8591C Cable TV Analyzer equipped with Option 107. When configured for cable television measurements, the system typically includes a baseband signal source, video modulator, four 75 Ω BNC interconnect cables, a 10 dB coupler, and the 85721A Cable TV measurements personality module. Female BNC connectors ensure straightforward integration into standard 75 Ohm test setups.
