Key Features of the HUADA SSMP-KK37 Connector

Frequency Range: The SSMP-KK37 operates in the frequency range from DC (direct current) up to an impressive 65 GHz1.
Impedance: It maintains a 50 Ω impedance, which is crucial for efficient signal transmission in high-frequency applications.
VSWR (Voltage Standing Wave Ratio): The VSWR is calculated as (1.02 + 0.012 times F) (where (F) represents the frequency in GHz). This parameter reflects how well the connector matches the impedance of the system.
Insertion Loss: The insertion loss is approximately (0.04 times sqrt{F}) (in GHz). Lower insertion loss indicates better signal integrity.
Dielectric Withstanding Voltage (DWV): The SSMP-KK37 can withstand up to 325 Vrms without compromising its performance.
Insulation Resistance: It boasts an insulation resistance of at least 5000 MΩ, ensuring minimal leakage and reliable operation.
Force to Engage and Disengage: Detent engagement requires a maximum force of 6.5 lbs, while smooth bore engagement needs no more than 2.5 lbs.
For disengagement, detent mode requires a minimum force of 4 lbs, and smooth bore mode requires just 1.5 lbs.
Misalignment Tolerance: Radial misalignment: ±0.010 inches
Axial misalignment: 0.000 to 0.010 inches
Temperature Range: The SSMP-KK37 can handle temperatures from -55°C to +165°C.
Environmental Testing: It meets various MIL-STD-202 standards, including thermal shock, moisture resistance, corrosion, vibration, and shock1.
