ZX85-40W-63-S+

Overview

The ZX85-40W-63-S+ is a coaxial bias-tee from the Mini-Circuits ZX85 series, designed for high-power RF applications. It operates within a frequency range of 700 MHz to 6 GHz and maintains a 50 Ohm impedance. The component features SMA connectors on all three ports (input, output, and DC). It supports a maximum continuous RF power handling of 40 Watts. Voltage Standing Wave Ratio (VSWR) specifications are typically 1.1:1 and 1.2:1 across the operating band.

Feature Summary

• High power handling capability up to 40 Watts for robust system operation
• Wide operational bandwidth covering 700 MHz to 6 GHz
• Standard SMA interface connectors for straightforward integration

Applications

• High power amplifier systems
• Repeater stations
• Transmit antenna configurations

Procurement Notes

Verify the specific datasheet version for the ZX85-40W-63-S+ prior to ordering, as Mini-Circuits may update electrical characteristics or mechanical drawings over time. Confirm that the 40W power rating aligns with your system's peak and average power requirements. Ensure connector gender and polarity match your existing cable infrastructure. Check for any recent supply chain advisories or lead time changes directly from authorized distributors.

Selection Notes

Select this model when high RF power handling is critical within the 700 MHz to 6 GHz spectrum. Compare VSWR performance against other bias-tees if signal integrity is paramount. Consider the SMA connector type for compatibility with standard test equipment and cabling. Evaluate thermal management needs given the 40W power dissipation. Alternative lower-power models exist if the 40W rating exceeds actual system requirements.

Part Context

This component belongs to the ZX85 series of bias-tees from Mini-Circuits, which are engineered for general-purpose RF applications requiring reliable DC injection. The series includes various models with different power ratings and frequency ranges. The ZX85-40W-63-S+ specifically addresses high-power scenarios, distinguishing it from lower-wattage variants in the same family.

Replacement Considerations

Direct substitutes include other ZX85 series models such as ZX85-40G-S+ or ZX85-63-S+, depending on specific frequency or power adjustments. Verify that alternative part numbers maintain the required 40W power handling and SMA connectivity. Cross-reference datasheets to ensure VSWR and frequency range specifications meet application constraints.
