Key Features of the ZMDC-37SN Connector

Frequency Range and Signal Integrity: The ZMDC-37SN operates across a frequency range spanning from 0.2 MHz to 250 MHz. This wide bandwidth ensures reliable signal transmission, making it suitable for applications such as data communication, instrumentation, and RF systems.
Its low mainline loss (insertion loss) of approximately 0.35 dB minimizes signal degradation, maintaining data integrity even at higher frequencies.
Coupling Efficiency: The connector’s in-out coupling efficiency is crucial for applications like power dividers and directional couplers. At 0.2 MHz, the coupling between input and output ports is around 19.44 dB, gradually increasing to 19.58 dB at 250 MHz. This precise coupling ensures efficient power transfer and minimal signal leakage.
Directivity and Isolation: Directivity matters when dealing with coupled signals. The ZMDC-37SN exhibits excellent directivity, typically achieving 33 dB. This means that it effectively separates the coupled signal from the mainline, reducing interference and crosstalk.
High directivity ensures that the connector efficiently routes signals without compromising overall system performance.
Power Handling Capability: With a robust design, the ZMDC-37SN can handle up to 4W of input power. Whether in high-power RF amplifiers or microwave systems, this connector maintains stability and reliability.
Temperature Resilience: Operating temperatures ranging from -55°C to +125°C make the ZMDC-37SN versatile across various environments. From frigid outdoor installations to industrial machinery, it remains steadfast.
Mechanical Endurance: The connector’s mechanical life spans 500 cycles. This durability ensures longevity, especially in applications where frequent connections and disconnections occur.
