SA18N25WA-20

Attenuators Overview

The SA18N25WA-20 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It provides a nominal attenuation of 20 dB with a 50 Ohm impedance. The device features N-type connectors, specifically Male (Plug) to Female (Jack). It is rated for 25 Watts of power handling and includes a heatsink body for thermal management. The Voltage Standing Wave Ratio (VSWR) is specified at 1.35. The unit operates within a temperature range of -55°C to +125°C.

Attenuators Feature Summary

• Incorporates a heatsink body for effective thermal dissipation during high-power operation.
• Maintains a low VSWR of 1.35 across the operational frequency band.
• Utilizes robust N-type connector interfaces for secure signal transmission.

Attenuators Applications

• RF signal level reduction in microwave test and measurement setups
• Impedance matching and signal conditioning in wireless communication systems
• Protection of sensitive receiver components from high-power signals

Attenuators Procurement Notes

Verify the specific connector gender configuration and power rating against system requirements before integration. Confirm that the 25-watt power handling capacity aligns with peak signal levels. Ensure the operating temperature range meets environmental conditions. Cross-reference the datasheet for precise mechanical dimensions to verify fitment within the assembly.

Attenuators Selection Notes

Select this component when a 20 dB attenuation value is required within an 18 GHz bandwidth. Consider the 25-watt power rating for high-power applications. The N-type interface dictates compatibility with existing connector infrastructure. Evaluate the heatsink design necessity for thermal management in enclosed spaces compared to lower-power variants.

Attenuators Part Context

This part belongs to the Fairview Microwave series of connectorized attenuators. It shares the N-type interface family with models like SA18NMNF25W-20 but differs in specific connector gender combinations and potentially internal construction details. It serves as a passive component within broader RF subsystem architectures requiring precise signal attenuation.
