The Agilent/Keysight N9356C is a bi-directional broadband power limiter that protects sensitive RF and microwave instruments from excess RF power, DC transients, and ESD. Operating across 10 MHz to 26.5 GHz, it integrates DC blocking on both input and output ports to eliminate subsonic interference while maintaining minimal insertion loss.
Technical Specifications
• Frequency Range: 10 MHz to 26.5 GHz
• Limiting Threshold: 25 dBm (typical)
• Maximum Continuous RF Input Power: 4 W
• Insertion Loss: < 2.25 dB
• Turn-on Time: < 100 ps
• Impedance: 50 ohms
• Connectors: 3.5 mm (male/female)
• Operating Temperature Range: 0 to +55 °C
– Key Features
• Integrated DC block on input and output ports rejects signals below 10 MHz
• Fast transient response with turn-on time under 100 ps
• Low insertion loss design minimizes measurement uncertainty
• Bi-directional configuration for flexible signal routing
• Fail-safe operation: opens or shorts to ground at high power levels to protect downstream equipment
– Typical Applications
• Network analyzer protection
• Spectrum analyzer input protection
• Amplifier safeguarding
• RF and microwave test system integration
– Compatibility & Integration
Designed for Keysight microwave and RF test systems. The 3.5 mm connector interface and 50-ohm impedance ensure seamless integration with standard laboratory RF equipment.
