SA18H-07

Attenuators Overview

The SA18H-07 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It provides a nominal attenuation of 7 dB with a 50 Ohm impedance. The device features SMA male (plug) to SMA female (jack) connectors and is rated for 2 Watts of continuous power. Constructed with a passivated stainless steel body, it maintains a VSWR of 1.35:1. The unit operates within a temperature range of -54°C to +125°C.

Attenuators Feature Summary

• Fixed 7 dB attenuation performance across the DC to 18 GHz frequency range
• SMA male to SMA female connector configuration for direct interconnection
• Passivated stainless steel housing for durability and environmental resistance
• Rated for 2 Watts continuous power handling capability

Attenuators Applications

• RF signal level reduction in test and measurement setups
• Impedance matching and signal conditioning in microwave circuits
• Protection of sensitive receiver inputs from high power signals
• Integration into modular RF instrumentation systems

Attenuators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required connector types and power ratings. Confirm that the passivated stainless steel construction meets environmental requirements for the intended deployment. Cross-reference the 18 GHz frequency limit and 2 Watt power rating with system specifications to prevent operational exceedance during procurement validation.

Attenuators Selection Notes

Select this component when a precise 7 dB attenuation value is required within an SMA-based infrastructure operating up to 18 GHz. The 2 Watt power rating suits moderate signal levels, while the stainless steel body offers robustness. Ensure the male-to-female interface aligns with existing cabling and fixture configurations. Consider thermal management if ambient temperatures approach the upper operational limit of 125°C.

Attenuators Part Context

This part belongs to the SA18H series of connectorized attenuators from Fairview Microwave. The series utilizes SMA interfaces and stainless steel bodies to provide reliable attenuation solutions in high-frequency environments. The model number indicates the specific attenuation value and connector configuration within this standardized product line.

Attenuators Replacement Considerations

Direct substitutes include other 7 dB SMA fixed attenuators with equivalent 2 Watt power ratings and 18 GHz bandwidth. Verify mechanical dimensions and VSWR specifications to ensure seamless integration without re-engineering the host assembly.
