SA4014-20

Attenuators Overview

The SA4014-20 is a fixed RF attenuator manufactured by Fairview Microwave, designed for high-frequency signal management. It features a 2.92mm connector interface, specifically a plug-to-jack configuration, ensuring compatibility within precision microwave systems. The component provides a nominal attenuation value of 20 dB across a frequency range extending from DC to 40 GHz. Constructed with a stainless steel body, it supports an input power rating of 1 Watt and maintains a 50 Ohm impedance. The unit is rated for operation between -55°C and +125°C, offering robust performance in demanding environments.

Attenuators Feature Summary

• Provides precise 20 dB signal attenuation for controlled power levels
• Operates effectively across a wide bandwidth from DC to 40 GHz
• Features durable stainless steel construction for environmental resilience

Attenuators Applications

• High-frequency test and measurement setups requiring signal reduction
• Microwave communication systems needing precise power level control
• RF circuit design involving signal conditioning and isolation

Attenuators Procurement Notes

Verify the specific connector gender configuration and physical dimensions against system requirements before ordering. Confirm that the 1 Watt power handling capacity aligns with peak operational signals. Ensure the operating temperature range meets environmental conditions. Check for RoHS compliance status if required by project specifications. Validate supplier authenticity through authorized distribution channels.

Attenuators Selection Notes

Select this model when a fixed 20 dB attenuation is necessary within a 50 Ohm system up to 40 GHz. Consider the 2.92mm interface for high-density or high-performance applications. Evaluate thermal management needs given the 1 Watt power limit. Compare against adjustable alternatives if variable attenuation is occasionally required. Assess mechanical fit within existing chassis or cable assemblies.

Attenuators Part Context

This component belongs to Fairview Microwave's line of fixed attenuators, which are essential passive devices for managing signal strength. Fixed attenuators like the SA4014-20 provide stable, non-variable loss, unlike programmable variants. They are distinct from amplifiers or switches, serving purely to reduce amplitude. This category ensures consistent impedance matching while lowering power levels to protect sensitive downstream components.

Attenuators Replacement Considerations

Direct substitutes must match the 20 dB attenuation value, 2.92mm interface, and 40 GHz frequency limit. Verify identical 50 Ohm impedance and 1 Watt power rating. Stainless steel body material aids in finding compatible replacements with similar durability. Check manufacturer datasheets for pin-out and dimensional equivalence to ensure seamless integration.
