4308-52

Attenuators Overview

The pSemi 4308-52 is an UltraCMOS RF attenuator designed for high-performance signal control applications. It provides a fixed attenuation value of 31 dB with a characteristic impedance of 75 Ohms, ensuring precise signal level management in RF circuits. The device operates effectively across a frequency range from 0 Hz to 2 GHz, making it suitable for broadband applications requiring stable attenuation characteristics. Packaged in a compact 20-WFQFN exposed pad format, this component integrates advanced CMOS technology to deliver reliable performance in space-constrained designs while maintaining signal integrity across its specified operational bandwidth.

Attenuators Feature Summary

• UltraCMOS technology integration for enhanced RF performance
• Fixed 31 dB attenuation capability for precise signal control
• 75 Ohm impedance matching for standard RF system compatibility
• Broadband operation supporting frequencies up to 2 GHz

Attenuators Applications

• RF signal conditioning in communication systems
• Attenuation stages in test and measurement equipment
• Signal level adjustment in broadcast infrastructure
• Impedance matching networks in RF front-end modules

Attenuators Procurement Notes

Verify the exact part number 4308-52 against manufacturer datasheets to confirm specifications. Ensure compatibility with 75 Ohm system requirements and 2 GHz operational limits. Check package type 20-WFQFN for board layout alignment. Confirm RoHS compliance status if required by project standards. Validate supplier authenticity through authorized distribution channels to guarantee component quality and traceability.

Attenuators Selection Notes

Select this component when a fixed 31 dB attenuation is required at 75 Ohms within a 0 Hz to 2 GHz range. Consider the 20-WFQFN package size for PCB space constraints. Evaluate thermal performance due to the exposed pad design. Compare against variable attenuators if adjustable attenuation is needed instead of fixed values. Ensure the application does not exceed the specified frequency or power handling limits defined in the official documentation.

Attenuators Part Context

This component belongs to the UltraCMOS series by pSemi, specializing in RF integrated circuits. It represents a fixed-value attenuator solution within their portfolio, distinct from programmable or variable attenuation devices. The 4308-52 variant specifically targets 75 Ohm systems, differing from 50 Ohm counterparts in the same family. Its design leverages CMOS processes for cost-effective mass production while maintaining RF performance metrics suitable for professional telecommunications and broadcasting environments.

Attenuators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify cross-compatibility with other 31 dB, 75 Ohm, 20-WFQFN attenuators only if official equivalence data exists. Do not assume functional interchangeability with 50 Ohm variants or different attenuation values without explicit manufacturer confirmation.
