EDC21-24+

RF Directional Couplers Overview

The EDC21-24+ is a general-purpose RF directional coupler manufactured by Mini-Circuits, designed for operation within the 4 GHz to 20 GHz frequency range. It features a nominal coupling coefficient of 21 dB with a tolerance of ±2 dB and provides an isolation level of 26 dB. The component utilizes a 50 Ohm impedance system and is housed in a compact 24-VFQFN package with an exposed pad, measuring 4x4 mm. This surface-mount device supports SMD/SMT termination styles and operates reliably across a temperature range starting from -40°C, making it suitable for high-frequency signal monitoring applications.

RF Directional Couplers Feature Summary

• Provides precise 21 dB coupling for accurate signal sampling in broadband RF systems
• Operates effectively across a wide 4 GHz to 20 GHz frequency spectrum
• Features a compact 4x4 mm MCLP footprint for efficient board space utilization
• Ensures high isolation performance to minimize signal interference between ports

RF Directional Couplers Applications

• General-purpose RF signal monitoring and power measurement
• Feedback control loops in microwave communication systems
• Signal injection and extraction in test and measurement equipment

RF Directional Couplers Procurement Notes

Verify that the specific part number suffix matches the required package variant, as Mini-Circuits offers both packaged components and die versions (e.g., EDC21-24-D). Confirm RoHS compliance status and moisture sensitivity levels during sourcing. Ensure that the ordering documentation explicitly references the '+' suffix to guarantee lead-free manufacturing standards and current production availability from authorized channels.

RF Directional Couplers Selection Notes

Select this component when a fixed 21 dB coupling value is required for signals between 4 and 20 GHz. The choice is driven by the need for a small form factor compatible with dense PCB layouts. Consider the 26 dB isolation specification for applications requiring moderate port separation. Evaluate the thermal performance of the exposed pad design for heat dissipation needs in high-power environments.

RF Directional Couplers Part Context

This model belongs to Mini-Circuits' extensive portfolio of RF directional couplers, which are essential passive components for managing signal flow in wireless infrastructure. The EDC series typically utilizes MMIC technology to achieve consistent performance across wide bandwidths. As a standard product, it complements other Mini-Circuits filters and amplifiers in complete RF front-end designs.
