4302-51

Attenuators Overview

The pSemi 4302-51 is a 6-bit RF digital attenuator designed for high-performance signal control applications. It provides a fixed attenuation value of 31.5 dB across a frequency range from 0 Hz to 4 GHz. The device operates with a 50 Ohm impedance and is housed in a 20-WFQFN package with an exposed pad, facilitating efficient thermal management and compact integration into RF systems requiring precise signal power reduction.

Attenuators Feature Summary

• Provides fixed 31.5 dB attenuation for significant signal power reduction
• Operates effectively from DC up to 4 GHz frequency range
• Integrates 6-bit resolution within a compact surface-mount footprint

Attenuators Applications

• RF signal conditioning circuits
• Test and measurement equipment
• Wireless communication base stations

Attenuators Procurement Notes

Verify the specific ordering code against manufacturer documentation to ensure compatibility with system requirements. Confirm that the 20-WFQFN package dimensions align with PCB layout constraints. Ensure supply chain sources provide authentic components from authorized distributors to maintain performance integrity and reliability standards.

Attenuators Selection Notes

Select this component when a fixed, high-level attenuation of 31.5 dB is required rather than variable control. Consider the 4 GHz bandwidth limit for high-frequency applications. Evaluate the 20-WFQFN package for thermal dissipation needs and board space limitations compared to other attenuator families.
