SA03B75-15

Attenuators Overview

The SA03B75-15 is a fixed RF attenuator manufactured by Fairview Microwave, designed for signal attenuation in radio frequency circuits. It features BNC connectors with a male plug on one end and a female jack on the other, providing a secure connection interface. The component operates at a characteristic impedance of 75 Ohms, suitable for video and broadcast applications. It offers an attenuation value of 15 dB across a frequency range from DC to 3 GHz. The device is rated for continuous power handling up to 2 Watts and can withstand peak power levels of 1 Kilowatt. Constructed with a brass body finished in nickel plating and gold-plated contacts, it ensures durability and reliable performance.

Attenuators Feature Summary

• Provides precise 15 dB signal attenuation for RF systems
• Features BNC male-to-female connector configuration for standard interfacing
• Operates within a wide frequency spectrum extending to 3 GHz
• Built with a robust brass and nickel housing for environmental resilience

Attenuators Applications

• Video distribution networks requiring signal level adjustment
• Broadcast equipment testing and calibration setups
• RF measurement systems needing specific attenuation values
• Telecommunications infrastructure utilizing 75 Ohm impedance standards

Attenuators Procurement Notes

Verify that the required impedance matches your system's 75 Ohm design specifications before procurement. Confirm that the operating frequency range up to 3 GHz aligns with your application requirements. Ensure the 2 Watt continuous power rating is sufficient for your signal levels. Check for RoHS compliance if environmental regulations apply to your project. Validate connector compatibility with existing BNC cabling infrastructure.

Attenuators Selection Notes

Select this model when a fixed 15 dB attenuation is necessary in a 75 Ohm environment. Consider the BNC interface for ease of installation in standard rack or bench setups. Evaluate the 3 GHz bandwidth to ensure it covers your operational frequency needs. Assess the power handling capabilities against maximum expected signal strengths. Compare with adjustable attenuators only if variable attenuation is required instead of a fixed value.

Attenuators Part Context

This component belongs to the family of fixed RF attenuators produced by Fairview Microwave. It is part of a series offering various attenuation values and connector types. The product line targets professional audio, video, and data transmission markets. Similar models may offer different attenuation levels or connector configurations such as SMA or N-type. The brand specializes in high-performance interconnect solutions for demanding RF environments.

Attenuators Replacement Considerations

Direct substitutes include other 15 dB fixed attenuators with BNC connectors and 75 Ohm impedance. Models like SA03B75-06 or SA03B75-03 from the same manufacturer offer similar form factors but different attenuation values. Ensure any replacement maintains the 75 Ohm impedance to prevent signal reflection. Verify that the replacement supports the same frequency range and power ratings.
