ADC-25-4-75+

RF Directional Couplers Overview

The ADC-25-4-75+ is a surface-mount RF directional coupler manufactured by Mini-Circuits. It operates within a frequency range of 5 MHz to 1.25 GHz and features a nominal coupling factor of 25 ± 1 dB. The component is designed for 75 Ω systems and supports a maximum power handling capacity of 500 mW. It utilizes a 6-SMD, flat lead package configuration suitable for automated assembly processes.

RF Directional Couplers Feature Summary

• Provides precise signal sampling via fixed 25 dB coupling factor
• Optimized for 75 Ohm impedance matching environments
• Supports broadband operation from low VHF to UHF frequencies

RF Directional Couplers Applications

• Signal monitoring in broadcast transmission lines
• Power measurement setups requiring non-intrusive sampling
• Feedback loop detection in RF amplifier chains

RF Directional Couplers Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to ensure correct termination style and tolerance specifications. Confirm RoHS compliance status through current manufacturer declarations. Cross-reference the part number with authorized distributor catalogs to validate authenticity and traceability before procurement execution.

RF Directional Couplers Selection Notes

Select this component when a 75 Ohm system interface is required rather than standard 50 Ohm configurations. Ensure the operating frequency range aligns with the 5 MHz to 1.25 GHz specification. Verify that the 500 mW power rating meets the application's peak signal requirements without causing thermal degradation or performance deviation.

RF Directional Couplers Part Context

This device belongs to the ADC series of surface-mount directional couplers. It shares functional similarities with other models in the family but differs in coupling value and impedance characteristics. The series offers various coupling factors tailored for different signal sampling needs across broad frequency bands.

RF Directional Couplers Replacement Considerations

Direct substitutes include ADC-20-4-75+ and ADC-8-4-75+ from Mini-Circuits, which share identical package styles and frequency ranges but offer different coupling factors. Verify impedance compatibility and coupling accuracy requirements before substituting.
