SD3244

Overview

The SD3244 is a DC block manufactured by Fairview Microwave, designed for signal conditioning applications. It operates within a frequency range of 10 MHz to 18 GHz and features SMA connectors. The component exhibits an insertion loss of 0.5 dB and maintains a VSWR of 1.35:1. It supports a breakdown voltage of 200 V. This device serves as an inner DC block for RF systems requiring isolation.

Feature Summary

• Provides DC isolation while maintaining RF signal integrity across the specified bandwidth
• Utilizes SMA connector interface for standard integration
• Engineered for high breakdown voltage handling

Applications

• RF signal path DC blocking
• Signal conditioning in microwave systems
• Test and measurement equipment interfaces

Procurement Notes

Verify the specific suffix (e.g., SD3244A) against official datasheets to ensure compatibility with required connector types and mounting styles. Confirm that the 200 V breakdown voltage meets system safety requirements. Check for availability constraints as distribution status may vary by region. Ensure SMA interface matches existing cable assemblies.

Selection Notes

Select this component when DC isolation is required between 10 MHz and 18 GHz. Consider the 0.5 dB insertion loss impact on system gain. Verify that the SMA interface aligns with current design specifications. Evaluate the 200 V breakdown rating against operational voltage limits. Ensure physical dimensions fit the intended enclosure or chassis space.

Part Context

The SD3244 belongs to Fairview Microwave's line of RF adapters and signal conditioning components. It falls under the category of inner DC blocks with SMA connectors. This series supports frequencies up to 18 GHz, catering to microwave and millimeter-wave applications requiring reliable DC blocking without significant signal degradation.

Replacement Considerations
