SA2B75-20

Attenuators Overview

The SA2B75-20 is a fixed RF attenuator manufactured by Fairview Microwave. It features BNC male (plug) to BNC female (jack) connectors with a nominal attenuation of 20 dB. The component operates within a frequency range up to 2 GHz and maintains a VSWR of 1.15. It is rated for 2 Watts continuous power handling and supports peak power up to 1 KWatts. The impedance is 75 Ohms, and the unit weighs approximately 18.37 grams.

Attenuators Feature Summary

• Provides precise 20 dB signal attenuation in a compact form factor
• Ensures stable performance with low voltage standing wave ratio
• Supports high peak power loads alongside standard continuous ratings

Attenuators Applications

• RF test and measurement setups requiring specific load conditions
• Signal conditioning in 75 Ohm video or broadcast transmission lines
• Laboratory equipment interfacing for signal level adjustment

Attenuators Procurement Notes

Verify the exact part number SA2B75-20 against official Fairview Microwave documentation to confirm connector gender and impedance specifications. Ensure compatibility with 75 Ohm system requirements before integration. Check current distributor availability as stock levels may vary. Confirm that the 2 Watt continuous and 1 KWatt peak power ratings meet your specific application's thermal and electrical demands.

Attenuators Selection Notes

Select this component when a 75 Ohm impedance match is required for BNC interconnects. The 20 dB attenuation value suits applications needing significant signal reduction. Consider the 2 GHz maximum frequency limit for high-speed digital or RF signals. The robust power handling makes it suitable for environments with potential signal spikes.

Attenuators Part Context

This device belongs to the RF terminator and attenuator category from Fairview Microwave. It utilizes brass construction with trimetal plating and gold contacts for reliable conductivity. The product is packaged individually in bags. It falls under RF Interconnects and is designed for professional electronic testing and signal management environments.

Attenuators Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include models from Pasternack such as PE7379-20 and PE7380-20. Verify connector type and impedance matching before substitution.
