SA18H-05

Attenuators Overview

The SA18H-05 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It provides a nominal attenuation of 5 dB with a tolerance of ±0.30 dB. The component features SMA male (plug) to SMA female (jack) connectors and operates within a 50 Ohm impedance system. It is rated for a maximum power handling capacity of 2 Watts continuous wave. The unit utilizes a passivated stainless steel body and maintains a VSWR of less than 1.35:1 across its frequency range.

Attenuators Feature Summary

• Provides precise signal attenuation in the 5 dB range for RF circuitry
• Features SMA male to SMA female connector interface for standard integration
• Constructed with a passivated stainless steel body for durability
• Supports operation up to 18 GHz with low voltage standing wave ratio

Attenuators Applications

• RF instrumentation systems requiring signal level adjustment
• Test and measurement setups for calibration purposes
• Communication equipment signal path management
• Electronic testing environments needing fixed attenuation

Attenuators Procurement Notes

Verify the specific model designation SA18H-05 against official Fairview Microwave documentation to confirm the 5 dB attenuation value and SMA connector configuration. Ensure that the required 2 Watt power rating and 18 GHz frequency limit align with the intended application parameters before finalizing procurement decisions.

Attenuators Selection Notes

Select this component when a fixed 5 dB attenuation is required for SMA-based systems operating up to 18 GHz. Consider the 2 Watt power rating and passivated stainless steel construction for environmental compatibility. Verify impedance matching at 50 Ohms and ensure the VSWR specification meets the system's performance requirements.

Attenuators Part Context

This part belongs to the SA18H series of fixed attenuators from Fairview Microwave, which are characterized by their SMA connector interfaces and operation up to 18 GHz. The series offers various attenuation values, with the SA18H-05 specifically providing 5 dB of attenuation. These components are designed for reliable performance in RF applications requiring precise signal control.

Attenuators Replacement Considerations

Compatible substitutes include other 5 dB fixed attenuators with SMA male-to-female interfaces and similar frequency and power ratings. Verify that alternative parts meet the 18 GHz upper frequency limit and 2 Watt power handling capability. Ensure mechanical dimensions and connector gender match the existing system requirements.
