SA03B-20

Attenuators Overview

The SA03B-20 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 3 GHz. It provides a nominal attenuation of 20 dB with a power rating of 2 Watts. The device features BNC connectors, specifically a male plug on one side and a female jack on the other. Constructed with a brass nickel body, it ensures durability in standard environments. The unit operates within a temperature range of -55°C to +125°C and maintains an impedance of 50 Ohms.

Attenuators Feature Summary

• Provides precise 20 dB signal reduction for RF circuits
• Features BNC male-to-female connector interface
• Utilizes brass nickel housing for structural integrity

Attenuators Applications

• RF signal level adjustment in test setups
• Attenuation in microwave communication systems
• Integration into 50 Ohm coaxial circuitry

Attenuators Procurement Notes

Verify that the specific order matches the SA03B-20 designation to ensure correct BNC gender configuration. Confirm that the 2 Watt power rating aligns with system requirements. Check RoHS compliance status if environmental regulations apply. Ensure the operating frequency does not exceed 3 GHz. Validate physical dimensions against available mounting space.

Attenuators Selection Notes

Select this component when a 20 dB fixed loss is required between BNC interfaces. Consider the 2 Watt power limit for high-power applications. Evaluate the -55°C to +125°C temperature range for environmental suitability. Compare against other models if different connector types or higher power ratings are needed.

Attenuators Part Context
