SA18NFNF25W-10

Attenuators Overview

The SA18NFNF25W-10 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It provides a nominal attenuation of 10 dB with a maximum frequency of 18 GHz and operates within an impedance of 50 Ohms. The device features N-type connectors in a female-to-female configuration. It is rated for a power handling capacity of 25 Watts and maintains a Voltage Standing Wave Ratio (VSWR) of 1.6. The unit utilizes a heatsink body construction and supports an operating temperature range from -55°C to +125°C.

Attenuators Feature Summary

• Features a heatsink body design for thermal management
• Supports high power handling up to 25 Watts
• Provides stable signal attenuation across a wide frequency range

Attenuators Applications

• RF signal level reduction in test and measurement setups
• Signal conditioning in wireless communication systems
• Attenuation in microwave circuit testing environments

Attenuators Procurement Notes

Verify the specific connector gender and power rating against system requirements before ordering. Confirm that the 25-watt power handling capability aligns with peak signal levels in the application. Ensure the N-type female-to-female interface matches existing cabling infrastructure. Check datasheet specifications for VSWR limits to guarantee signal integrity at frequencies approaching 18 GHz.

Attenuators Selection Notes

Select this component when a 10 dB fixed attenuation value is required for N-type interfaces. Consider the 25-watt power rating for higher power applications compared to standard low-power variants. Evaluate the heatsink body requirement for thermal dissipation needs. Verify compatibility with the 0 Hz to 18 GHz operational bandwidth for broadband applications.

Attenuators Part Context

This model belongs to the Fairview Microwave series of connectorized attenuators. It is part of a family offering various attenuation values and connector types. The SA18NFNF25W-10 specifically addresses the need for robust, high-power attenuation in N-type configurations. It serves as a passive component for managing signal strength in RF networks.

Attenuators Replacement Considerations

SA18NMNF25W-10 offers identical electrical performance but uses male-to-female connectors instead of female-to-female. FMAT7604-10 is listed as a parameter equivalent alternative from the same manufacturer.
