MACP-011058

RF Directional Couplers Overview

The MACP-011058 is a general-purpose RF directional coupler manufactured by MACOM Technology Solutions. It operates within a frequency range of 5MHz to 1.25GHz and provides a nominal coupling coefficient of 10dB. The component supports a maximum power handling capacity of 2W. Key electrical specifications include an isolation rating of 42dB and a return loss of 25dB. The device is housed in a compact 5-SMD module package, designed for surface mount integration into RF circuits.

RF Directional Couplers Feature Summary

• Provides precise signal sampling via standard 10dB coupling architecture
• Ensures high port-to-port isolation to minimize signal interference
• Delivers stable impedance matching with specified return loss characteristics
• Utilizes a compact surface mount form factor for efficient PCB integration

RF Directional Couplers Applications

• CATV network monitoring and signal distribution
• Full Duplex communication systems
• DOCSIS 3.1 infrastructure implementations

RF Directional Couplers Procurement Notes

Verify the current availability status as distributor listings indicate potential discontinuation or limited supply conditions. Confirm RoHS3 compliance requirements against specific project constraints. Ensure the 5-SMD package dimensions align with the designated PCB footprint before finalizing orders. Request official datasheets to validate isolation and return loss parameters for critical design reviews.

RF Directional Couplers Selection Notes

Select this component when a 10dB coupling ratio is required for signal monitoring within the 5MHz to 1.25GHz band. The 2W power rating suits moderate power levels typical in cable television and broadband access networks. The surface mount package facilitates automated assembly processes. Verify that the 42dB isolation meets system crosstalk requirements for full duplex or DOCSIS applications.

RF Directional Couplers Part Context

This part belongs to MACOM's portfolio of passive RF components designed for high-performance signal processing.

RF Directional Couplers FAQ

What is the recommended transmission line width for the 5-SMD package?

The recommended PCB layout utilizes a grounded coplanar waveguide with a transmission line width of 0.70 mm and a gap of 0.57 mm on 1.6 mm FR4 material.

Does the component support high-power applications?

No, the maximum power handling capacity is rated at 2W, making it suitable for moderate power levels rather than high-power transmission lines.
