L157XG3S

Overview

The L157XG3S is a surface-mount low-pass RF filter manufactured by Knowles Dielectric Labs. It features a center frequency of 7.5 GHz and a bandwidth of 1.5 dB. The component operates at an impedance of 50 Ohms and utilizes a 6-SMD, no-lead package with dimensions of 5.59mm x 3.56mm x 2.62mm. It is designed for signal conditioning in high-frequency applications.

Feature Summary

• Provides low-pass filtering characteristics for radio frequency signals
• Utilizes a compact surface-mount package for board integration
• Designed for operation within standard industrial temperature ranges

Applications

• RF signal conditioning circuits
• Wireless communication systems
• Microwave frequency filtering

Procurement Notes

Verify the specific suffix (e.g., -T) required for your packaging needs, as availability varies between tape-and-reel and cut-tape formats. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the selected variant matches the exact pin configuration and footprint requirements of your design.

Selection Notes

Select this component when a 7.5 GHz center frequency and 1.5 dB bandwidth are required for low-pass filtering. Ensure the 50 Ohm impedance matches the system design. Consider the 6-SMD no-lead package size for space-constrained layouts. Verify thermal performance against the specified operating temperature range.

Part Context

This part belongs to the L157XG series of surface-mount low-pass filters from Knowles Dielectric Labs. These components are engineered for high-frequency signal integrity. The series offers various configurations tailored for different center frequencies and bandwidths in RF applications.

Replacement Considerations

Direct substitutes include other L157XG series variants such as L157XG3S-T. Evaluate alternative low-pass filters with matching 7.5 GHz center frequency and 50 Ohm impedance if sourcing constraints exist.
