Key Features of the ZMDC-39S1S Connector

Frequency Range: The ZMDC-39S1S operates across a broad frequency spectrum, spanning from 0.2 MHz to 250 MHz. This versatility makes it suitable for various applications, from data communication to RF systems.
Mainline Loss (Insertion Loss): When signals traverse the connector, they encounter a minimal mainline loss (insertion loss) of approximately 0.35 dB. This low attenuation ensures efficient signal transmission without compromising performance.
In-Out Coupling: The coupling factor between the input and output ports varies with frequency. Let’s explore the specifics:
At 0.20 MHz: The coupling loss is 0.55 dB, indicating effective isolation.
At 55.00 MHz: The coupling loss reduces to 0.28 dB, demonstrating improved signal transfer.
At 250.00 MHz: The coupling loss slightly increases to 0.44 dB, still maintaining excellent performance.
Directivity: Directivity matters when minimizing signal leakage between ports. The ZMDC-39S1S achieves an impressive directivity of approximately 33 dB. This ensures that transmitted signals remain focused and isolated.
Input Power Handling: With a maximum power handling capability of 4W, this connector can withstand high input power levels. Whether in demanding industrial environments or critical communication systems, it maintains robustness.
Temperature Resilience: The ZMDC-39S1S thrives in extreme temperature conditions. Its operational range spans from -55°C (frigid environments) to +125°C (hot environments), making it suitable for diverse applications.
