4306-52

Attenuators Overview

The pSemi 4306-52 is a high linearity, 5-bit RF Digital Step Attenuator (DSA) designed for precision signal control in radio frequency applications. It provides a total attenuation range of 31 dB with discrete steps of 1 dB, allowing for fine-grained adjustment of signal amplitude. The device operates from 0 Hz to 4 GHz and is characterized by a nominal impedance of 50 Ohms. It is housed in a compact 20-WFQFN package with an exposed pad, facilitating efficient thermal management and integration into space-constrained circuit boards.

Attenuators Procurement Notes

Verify the specific suffix code matches the required operating temperature range and packaging configuration. Confirm that the supplier provides original manufacturer documentation to ensure component authenticity. Check for any specific handling requirements related to the exposed pad thermal design during assembly.

Attenuators Selection Notes

Select this component when a 5-bit resolution with 1 dB step size is sufficient for the application's dynamic range requirements. Ensure the system impedance is matched to 50 Ohms to minimize reflections. Consider the 4 GHz upper frequency limit to verify compatibility with the intended signal bandwidth.
