Key Features of the HUADA SSMP(M)-JWHD3 RF Connector

Frequency Range: The SSMP(M)-JWHD3 operates seamlessly across an impressive frequency range, spanning from DC (direct current) to 65 GHz. This wide bandwidth ensures reliable signal transmission even in high-frequency applications.
Impedance and Signal Integrity: Maintaining a consistent 50 Ω impedance, this connector ensures optimal signal performance. Whether you’re dealing with data transmission, telecommunications, or radar systems, the SSMP(M)-JWHD3 keeps your signals in check.
VSWR (Voltage Standing Wave Ratio): The VSWR, a critical parameter for RF connectors, is calculated as 1.02 + 0.012 × F (GHz). A low VSWR indicates minimal signal reflection and efficient power transfer.
Insertion Loss: The insertion loss—approximately 0.04 × √F (GHz)—quantifies the signal attenuation as it passes through the connector. Lower insertion loss translates to better performance.
Dielectric Withstanding Voltage (DWV): The SSMP(M)-JWHD3 can withstand a maximum voltage of 325 Vrms. This robust dielectric design ensures durability and safety.
Insulation Resistance: With a minimum insulation resistance of 5000 MΩ, the connector maintains electrical isolation even under challenging conditions.
Engagement and Disengagement Forces: When connecting or disconnecting, the SSMP(M)-JWHD3 exhibits specific forces: Detent engagement: 6.5 lbs (max),Smooth bore engagement: 2.5 lbs (max)
Detent disengagement: 4 lbs (min),Smooth bore disengagement: 1.5 lbs (min)
Misalignment Tolerance: Radial misalignment (sideways): +/- 0.010 inches
Axial misalignment (along the axis): 0.000/0.010 inches
Temperature Range: The SSMP(M)-JWHD3 operates reliably in temperatures ranging from -55°C to +165°C. Whether it’s scorching heat or freezing cold, this connector won’t let you down.
Environmental Testing and Compliance: The SSMP(M)-JWHD3 adheres to various MIL-STD-202 standards, including thermal shock, moisture resistance, corrosion, vibration, and shock. It’s battle-tested for rugged environments.
