SA18N-12

Attenuators Overview

The SA18N-12 is a fixed RF attenuator manufactured by Fairview Microwave, designed for signal reduction in radio frequency systems. It provides a nominal attenuation of 12 dB across a frequency range extending from DC to 18 GHz. The component features N-type connectors configured as male plug to female jack. It is rated for 2 watts of power handling capacity and utilizes a passivated stainless steel body for durability. The unit maintains a 50 Ohm impedance with a Voltage Standing Wave Ratio (VSWR) of 1.3:1.

Attenuators Feature Summary

• Provides precise 12 dB signal attenuation for RF applications
• Operates effectively within a wide bandwidth up to 18 GHz
• Constructed with a passivated stainless steel housing for environmental resistance
• Supports standard N-type interconnection interfaces

Attenuators Applications

• RF signal level adjustment in test and measurement setups
• Attenuation stages in wireless communication infrastructure
• Signal conditioning in microwave circuit design
• Laboratory equipment requiring stable signal reduction

Attenuators Procurement Notes

Verify the specific connector gender configuration and power rating against system requirements before procurement. Confirm that the 2-watt power limit aligns with operational peak levels. Ensure compatibility with existing N-type cabling and fixtures. Check for RoHS compliance status if required by project specifications. Validate the 18 GHz upper frequency limit meets application bandwidth needs.

Attenuators Selection Notes

Select this model when a 12 dB attenuation value is required within an 18 GHz operational bandwidth. Choose based on the need for robust stainless steel construction and 2-watt power handling. Consider the N-type interface compatibility with current system components. Evaluate the 1.3:1 VSWR performance against system return loss requirements. Compare against other attenuation values if signal reduction needs differ.
