Key Features of the SMA-KFD432 HUADA Coaxial Connector

Impedance (50Ω): The SMA-KFD432 connector is meticulously engineered for a 50Ω impedance. This specific impedance value ensures optimal signal transfer efficiency, making it compatible with standard RF systems. Whether you’re connecting antennas, transceivers, or other RF components, this impedance match is critical for minimizing signal reflections and maximizing performance.
Operating Temperature Range: Picture this connector in action: it can withstand extreme temperature swings without breaking a sweat. From the icy depths of -65°C to the scorching heights of +165°C, the SMA-KFD432 remains steadfast. This versatility is invaluable for applications spanning outdoor environments, industrial machinery, and aerospace systems. No matter the climate, this connector won’t flinch.
Mating Cycles (500): Imagine plugging and unplugging a connector repeatedly—500 times, to be precise. That’s the robustness of the SMA-KFD432. Whether you’re setting up test equipment, configuring communication networks, or designing RF prototypes, this connector’s durability ensures longevity. It’s like having a reliable handshake that never weakens, even after countless interactions.
Insulation Resistance (5000 MΩ): Think of insulation resistance as the connector’s ability to keep secrets. In this case, the secret is the signal integrity. With an impressive 5000 MΩ insulation resistance, the SMA-KFD432 guards against leakage currents and stray paths. Your RF signals stay pristine, unaffected by unwanted leakage. It’s like having a trustworthy vault for your electrical secrets.
Dielectric Withstanding Voltage (1000 V): Voltage can be intimidating, but not for the SMA-KFD432. Its dielectric material stands tall against up to 1000 volts. Whether you’re dealing with high-frequency applications, power amplifiers, or medical devices, this connector ensures safety and reliability. It’s like having an electrically savvy bodyguard—protecting your circuits from voltage bullies.
Frequency Range:
Let’s talk frequencies. The SMA-KFD432 adapts seamlessly:
Flexible Cable: It dances across the spectrum from 0 to 12.4GHz. Picture it waltzing through Wi-Fi bands, cellular networks, and satellite communication.
Semi-rigid: Here, the dance floor expands. From 0 to 18GHz, it grooves with microwave signals, radar systems, and high-speed data links. It’s like having a connector that knows all the right moves, no matter the tempo.
VSWR (Voltage Standing Wave Ratio):
VSWR is the connector’s reflection coefficient—a measure of how well it handles signal reflections. The SMA-KFD432 nails it:
Flexible Cable: VSWR stays low at 1.15 + 0.02F (where F is the frequency in GHz). It’s like having a mirror that reflects only the good vibes.
Semi-rigid: Even better—VSWR is 1.10 + 0.02F. It’s like having a polished surface that enhances your signal’s self-esteem.
