FMCP1025-20

RF Directional Couplers Overview

The FMCP1025-20 is an SMA directional coupler manufactured by Fairview Microwave, designed for signal conditioning applications within the 800 MHz to 2.5 GHz frequency range. It provides a nominal coupling factor of 20 dB with a variation of ±1 dB. The component is rated for up to 50 Watts of power handling capacity and features standard SMA connectors. It operates reliably across a temperature range of -45°C to +85°C and maintains a 50 Ohm impedance. Packaged individually in bags, this active device supports general-purpose RF testing and measurement environments.

RF Directional Couplers Feature Summary

• Provides precise signal sampling via a 20 dB coupling factor with tight tolerance
• Supports high-power applications with a 50 Watt rating
• Operates across a broad microwave frequency spectrum from 800 MHz to 2.5 GHz
• Utilizes robust SMA connectors for reliable interconnection

RF Directional Couplers Applications

• General-purpose RF signal monitoring
• Power measurement systems requiring signal sampling
• Test and measurement equipment signal routing

RF Directional Couplers Procurement Notes

Verify that the required coupling tolerance of ±1 dB aligns with system specifications. Confirm that the 50 Watt power rating exceeds maximum operational levels to prevent damage. Ensure SMA connector compatibility with existing cabling infrastructure. Check availability status as supply may be restricted in certain regions. Validate operating temperature requirements against environmental conditions.

RF Directional Couplers Selection Notes

Choose this model when a 20 dB coupling value is specifically required for signal attenuation or sampling. Select based on the 800 MHz to 2.5 GHz bandwidth covering target frequencies. Consider the 50 Watt power handling capability for high-power transmission lines. Verify SMA interface compatibility with system connectors. Evaluate thermal performance needs against the -45°C to +85°C operating range.

RF Directional Couplers Part Context

This component belongs to Fairview Microwave's line of RF directional couplers, which are essential passive components for managing signal flow in wireless communication systems. These devices enable accurate power monitoring without disrupting main signal paths. The FMCP1025 series offers standardized SMA interfaces suitable for laboratory and field deployments requiring consistent performance across microwave frequencies.

RF Directional Couplers Replacement Considerations

The FMCP1025-10 serves as a functional substitute if a 10 dB coupling factor is acceptable instead of 20 dB. Both models share identical frequency ranges, power ratings, and connector types. Verify that the specific coupling requirement matches the replacement part's specification before substitution.
