Key Features of the HUADA SMP-KY89-1 Connector
Impedance: The SMP-KY89-1 connector has an impedance of 50 Ohms, making it suitable for high-frequency applications.
Frequency Range: It operates across a wide frequency range, from DC (direct current) up to 40 GHz. This versatility allows it to handle various signal types and applications.
VSWR (Voltage Standing Wave Ratio): The VSWR is a critical parameter for signal integrity. Here are the maximum VSWR values for different frequency bands: Up to 18 GHz: 1.20 (excellent performance)
18 to 26.5 GHz: 1.35 (still very good)
26.5 to 40 GHz: 1.70 (maintains reasonable performance)
Temperature Range: The SMP-KY89-1 connector can withstand extreme temperatures, operating from -65°C to +165°C. This robust temperature range ensures reliability in harsh environments.
Body Materials: The outer shell of the connector is made of brass with black nickel plating. This combination provides durability and corrosion resistance.
Inner components are also brass (per ASTM B16), ensuring mechanical strength.
Contact Materials: Male contacts are brass with gold plating. Gold plating enhances conductivity and prevents oxidation.
Female contacts use phosphor bronze with BECU (beryllium copper) gold plating. These materials maintain excellent electrical performance.
Insulator: The insulator material is PTFE (Polytetrafluoroethylene). PTFE is known for its low dielectric constant, high insulation resistance, and chemical inertness.
Durability: The connector’s durability is crucial for repeated mating cycles. Here are the durability specifications:Full Detent: 100 cycles
