L117XH4W

Overview

The L117XH4W is a low-pass RF filter manufactured by Knowles Dielectric Labs, designed for signal conditioning applications. It features a cutoff frequency of 11.0 GHz and operates with a standard 50 Ohms impedance. The component utilizes wirebond technology for connection, distinguishing it from surface-mount variants in the same series. This design supports board mounting and is intended for high-frequency radio frequency environments requiring precise spectral filtering.

Feature Summary

• Provides low-pass filtering characteristics with an 11.0 GHz cutoff frequency
• Utilizes wirebond interconnect technology for circuit integration
• Maintains a 50 Ohms system impedance for RF compatibility

Applications

• Radio frequency signal conditioning circuits
• High-frequency wireless communication systems
• Spectral filtering in RF front-end modules

Procurement Notes

Verify the specific suffix designation when ordering, as the base model L117XH4W differs from the tape-and-reel variant L117XH4W-T. Confirm wirebond termination requirements against your PCB layout capabilities. Ensure the 11.0 GHz cutoff specification aligns with your system's bandwidth needs rather than assuming higher frequency ratings found in other series members.

Selection Notes

Select this component when wirebond integration is preferred over surface-mount assembly for RF filtering tasks. The 11.0 GHz cutoff defines its operational limit, making it suitable for applications below this threshold. Compare physical dimensions and bond pad layouts against available ECAD models to ensure mechanical fit within the target enclosure or module design constraints.

Part Context

This part belongs to the Knowles Dielectric Labs low-pass filter family, which includes various frequency-specific models. While similar to the L117XH4W-T, the non-taped version may have different handling or packaging specifications. It shares the core dielectric technology used across the brand's RF components but is distinct from their bandpass filters like the B121MB4S.

Replacement Considerations

The L117XH4W-T serves as a functional equivalent with identical electrical performance but differs in packaging format. Verify that the receiving equipment supports wirebond connections if replacing surface-mount alternatives.
