SA18N25WA-30

Attenuators Overview

The SA18N25WA-30 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It provides a nominal attenuation of 30 dB with a 50 Ohm impedance. The device features Type N male-to-male connectors and is rated for 25 Watts of power handling. It incorporates a heatsink body to manage thermal dissipation and maintains a VSWR of 1.6. The unit operates within a temperature range of -55°C to +125°C and measures 114.3 mm in length.

Attenuators Feature Summary

• Fixed 30 dB attenuation performance across the DC to 18 GHz frequency range
• Type N male connector interface on both input and output ports
• Heatsink body construction for enhanced thermal management at 25 Watt ratings
• Wide operational temperature capability from -55°C to +125°C

Attenuators Applications

• RF signal level reduction in high-frequency test setups
• Attenuation in microwave communication systems operating up to 18 GHz
• Integration into measurement chains requiring precise signal power control

Attenuators Procurement Notes

Verify the specific datasheet for the SA18N25WA-30 to confirm current manufacturing status and detailed mechanical drawings. Ensure that the Type N male-to-male configuration aligns with system interconnect requirements. Confirm thermal management needs are met by the heatsink design given the 25 Watt power rating. Check for any specific environmental certifications or compliance documentation required for the intended deployment environment.

Attenuators Selection Notes

Select this component when a fixed 30 dB attenuation value is required within an 18 GHz bandwidth. The Type N male-to-male interface dictates compatibility with existing male-ended coaxial infrastructure. The 25 Watt power rating and heatsink body make it suitable for higher power applications compared to standard unheated attenuators. Consider the physical length of 114.3 mm for spatial constraints in the assembly.

Attenuators Part Context

This part belongs to the Fairview Microwave series of connectorized attenuators. It is distinct from female-female variants like the SA18NFNF25W-30 due to its male-to-male connector configuration. The model designation indicates a 30 dB attenuation value, 18 GHz frequency limit, 25 Watt power rating, and Type N connectors. It serves as a passive component for signal conditioning in RF circuits.
